RESEARCH OVERVIEW

Overview of React

React is a powerful UI library created by Facebook, designed for building highly interactive and reusable UI components Its versatility allows it to function on both the client and server sides, enabling seamless integration By efficiently comparing changes between renders, React updates the DOM with minimal alterations, enhancing performance and user experience.

Virtual DOM technology significantly boosts application performance by ensuring that only the root node maintains state When this state changes, it triggers a complete restructuring of the DOM tree, impacting processing speed React JS leverages Virtual DOM to address these issues effectively Essentially, Virtual DOM is a JavaScript object that encapsulates all necessary information for creating a DOM Upon data changes, it calculates the differences between the virtual object and the actual DOM tree, optimizing the re-rendering process for enhanced efficiency.

React employs a one-way data binding mechanism, allowing data to flow seamlessly from parent components to child components through props This straightforward data flow simplifies error management and enhances control over the application Due to these features, React is ideal for developing large-scale applications that require continuous data updates, with changes in data often reflecting updates in the user interface.

JSX is a powerful language that enables developers to write HTML code within JavaScript, offering significant advantages It enhances performance by optimizing code during compilation, resulting in faster execution compared to traditional JavaScript Additionally, JSX's static typing allows for early error detection during compilation, similar to languages like Java and C++, leading to improved security and robust debugging capabilities.

React is fundamentally structured around components rather than templates, allowing developers to create websites using small, reusable components Each component can have different states or properties and can contain other components, enabling a flexible architecture Additionally, every component in React maintains its own mutable state, with updates triggered by changes in that state, making components the core building blocks of React applications.

They help maintain code when working on large projects A simple react component just needs a render method There are many other methods available, but render is the dominant method.

Props: helps components interact with each other, the component takes input called props, and returns properties that describe what the child component should render Prop is immutable.

State: represents the state of the application, when the state changes, the component also re-renders to update the UI.

ReactJs

React JS is a powerful JavaScript library designed for building user interfaces (UIs) on both web and mobile platforms Developed by Facebook, React boasts a rich ecosystem and is widely adopted in the industry Its primary goal is to enable the creation of fast, efficient, and visually appealing web applications with minimal coding React ensures that websites function smoothly, load quickly, and maintain high scalability, making it simple to implement in various projects.

ReactJS utilizes a virtual DOM to enhance performance by allowing components to reside within it When updates or changes are required, ReactJS first performs calculations in the virtual DOM, minimizing direct manipulations of the actual DOM This efficient approach reduces unnecessary operations and optimizes rendering, ultimately improving the overall performance of applications built with ReactJS.

ReactJS simplifies JavaScript coding through its unique JSX syntax, enabling the seamless integration of HTML and JavaScript This feature allows developers to incorporate additional code directly within the render function, eliminating the need for string concatenation and enhancing the overall coding experience.

ReactJS and converting HTML fragments into constructors are all implemented from the main converter which is JSX.

ReactJS stands out as a highly SEO-friendly JavaScript framework, addressing a significant challenge faced by many other frameworks that struggle with search engine optimization Unlike its counterparts, ReactJS leverages server-side rendering and the Virtual DOM, enabling it to deliver content that is easily indexed by search engines This capability ensures that React applications are not only performant but also optimized for search visibility, making it a preferred choice for developers focused on SEO.

ReactJS is primarily a View library, distinct from traditional MVC frameworks, as it focuses solely on rendering the view layer Developed by Facebook, React does not include Model and Controller components, necessitating integration with other libraries for a complete solution Additionally, React lacks features like two-way data binding and built-in Ajax support.

Integrating React.js into traditional MVC frameworks necessitates a reconfiguration process due to its size, which is comparable to Angular, with React being approximately 35kb and Angular around 39kb However, while React is a robust library, Angular offers a more comprehensive framework solution.

1.2.4 Things to know about React Js:

ReactJS enables the creation of highly interactive, stateful, and reusable UI components It operates seamlessly on both the client side and server side, allowing for effective integration between the two Notably, React is not an MVC framework; it lacks a built-in model and controller, requiring the use of additional libraries for data manipulation.

Minimizing the use of State components is crucial, as the State serves as the core of an application's functionality It's essential to keep the State simple due to the continuous growth of React applications Excessive State can complicate testing and affect rendering, particularly in terms of whether the data has been initialized or changed Additionally, State is confined to individual components and should only be used when necessary to accurately represent the component's state and facilitate data exchange.

React, primarily a view library, is most effective when paired with state management tools like Redux or Flux, enhancing its data flow capabilities Redux is a popular choice among developers for managing application state JSX, a standout feature of React, allows developers to write HTML-like syntax directly in their JavaScript, while Babel compiles this code, enabling the use of modern ES6 features Additionally, NPM and Webpack are essential for packaging and optimizing libraries, streamlining the development process.

NodeJS is a platform that enables faster and independent website development, as it does not require waiting for API responses, making its APIs asynchronous It is compatible with multiple operating systems, including Windows, MacOS, and Linux However, it operates as a single-threaded server, which means it does not support multi-threading.

NodeJS is not classified as a programming language, so beginners should have a solid understanding of fundamental programming concepts, including protocols and JavaScript, to effectively utilize NodeJS The NodeJS community is extensive and offers support at any time Built primarily in C++, NodeJS boasts high performance and processing speed, enabling applications to respond in real-time across multiple platforms and devices.

Node.js offers exceptional execution speed and scalability, making it an ideal choice for startups aiming to develop large products Its performance is crucial for accommodating a growing user base, ensuring that your site can scale efficiently as demand increases.

Asynchronous event-driven IO helps handle multiple concurrent requests Meet real-time requirements Has extremely fast speed, meeting the usage needs of 'huge' visitors in a short time.

Use JavaScript, a programming language that is very easy to learn Share the same piece of code with both server and client side.

Npm and its modules are continually evolving, supported by a robust community and extensive code sharing on GitHub They offer compatibility across various devices and operating systems, including MacOS, Windows, and Linux.

Implementing Node.js on a host can be challenging, especially with shared web hosting, as it doesn't support direct Node.js application deployment For optimal performance, using a VPS or dedicated server is recommended, allowing for proper installation and management of Node.js applications.

One significant disadvantage of Node.js is its ongoing development phase, leading to potential changes in features over time This evolving nature is highlighted by the stability index found in various articles, indicating the risks associated with using its current functionalities.

NodeJS struggles with scalability and fails to utilize the multi-core capabilities of modern server-grade hardware, making it challenging to work with relational databases.

Using callbacks in JavaScript can lead to complex nested structures, making it challenging for those unfamiliar with the language, especially when working with Node.js It's important to note that Node.js is optimized for I/O operations, such as web servers, rather than CPU-intensive tasks.

Python

Python is a versatile programming language commonly utilized in web applications, software development, data science, and machine learning Its efficiency, ease of learning, and compatibility with multiple platforms make it a popular choice among developers.

Python is an interpreted programming language that executes code line by line This allows for immediate error detection, as the execution halts upon encountering a mistake, enabling programmers to quickly identify and fix issues in their code.

Python uses the same word as in English Unlike other programming languages, Python does not use braces Instead, this language uses indentation.

Programmers do not need to declare variable types when writing code because Python will determine them at run time So you can write Python programs more quickly.

Python is closer to the human language than other programming languages. Therefore, programmers do not need to worry about its basic functions such as architecture and memory management.

Developers can easily read and understand a Python program because the language has the same basic syntax as English.

Python improves the productivity of developers because compared to other languages, they can use fewer lines of code to write a Python program.

Python boasts an extensive standard library filled with reusable code, allowing developers to avoid starting from scratch for various tasks Additionally, it seamlessly integrates with other widely-used programming languages such as Java, C, and C++.

The active Python community includes millions of enthusiastic developers around the world If you run into problems, you'll be able to get quick support from the community.

There are many useful resources on the Internet if you want to learn Python. For example, you can easily find developer videos, tutorials, documentation, and guides.

Python can be used on many different computer operating systems, such as Windows, macOS, Linux, and Unix.

Although it is a faster language than PHP, Python is quite slow compared to C/C++ and JavaScript.

Only use Python to create programs that work on the web platform, but cannot integrate program development on mobile devices.

Does not contain properties such as public, protected or private In particular,do while loops cannot be performed with switch case.

Recommender system

Recommender Systems are a leading application of data science, widely utilized to forecast user ratings or preferences for various items Today, nearly every major technology company has integrated these systems into their services, highlighting their significance in enhancing user experience and engagement.

Step 1: Find features that influence user ratings, through data exploration and analysis

Step 2: Analyze and apply suitable filtering algorithm

Simple recommenders provide broad suggestions for all users, focusing on popular films and specific genres This system operates on the premise that movies with high popularity and critical acclaim are more likely to resonate with a general audience A prime example of this is the IMDB Top 250 list, which highlights films that appeal to a wide range of viewers.

Content-based recommenders suggest similar items by analyzing specific item metadata, including genre, director, description, and actors These systems operate on the principle that if a user enjoys a particular item, they are likely to appreciate similar items By leveraging the user's past interactions and preferences, these recommenders provide tailored suggestions A prime example of this is YouTube, which recommends new videos based on your viewing history.

Figure 1.4 - Main types of recommender

Collaborative filtering recommenders are popular systems that predict user ratings or preferences for items by analyzing the past ratings and preferences of other users Unlike content-based filters, these systems do not rely on item metadata, making them efficient in generating personalized recommendations.

Hybrid recommenders combine content-based filtering and collaborative filtering algorithms to enhance recommendation systems This approach allows flexibility; when collaborative filtering lacks user behavior data, the system relies on content-based filtering, and conversely, when content-based filtering lacks necessary features, collaborative filtering takes precedence.

The correlation coefficient is a statistical indicator that measures the strength and weakness of the relationship between two variables.

The correlation coefficient has a value from -1.0 to 1.0 A calculated result greater than 1.0 or less than -1 means there is an error in the correlation measurement.

 A negative correlation coefficient shows that two variables have an inverse or negative relationship (absolutely inverse when the value is -1).

 A positive correlation coefficient indicates a positive or positive relationship (absolute covariance when the value is equal to 1).

 Correlation is zero for two independent variables.

1.5.5 What does Pearson coefficient mean?

Pearson correlation coefficient (r) fluctuates in the continuous range from -1 to +1:

 r = 0: Two variables have no linear correlation

 r = 1; r = -1: Two variables have an absolute linear relationship.

 r < 0: Negative correlation coefficient That is, the value of variable x increases, the value of variable y decreases and vice versa, the value of variable y increases, the value of variable x decreases.

 r > 0: Positive correlation coefficient That is, the value of variable x increases, the value of variable y increases and vice versa, the value of variable y increases, the value of variable x also increases.

 If r is between 0.50 and ±1, it is said to be strongly correlated.

 If r is between 0.30 and ±0.49, then it is called the mean correlation.

 If r is below ±.29, then it is called a weak correlation.

 On a scatter plot, if r = -1 the data will be distributed on a straight line with a negative slope, r = 1 the data will be distributed on a straight line with a positive slope.

Figure 1.6 - Strength of the pearson correlation coefficient

Implementation tools

Visual Studio Code, developed by Microsoft, is a versatile code editor compatible with Windows, Linux, and macOS It offers robust features such as debugging support, integrated Git functionality, syntax highlighting, intelligent code completion, and various code enhancements, making it an essential tool for developers.

XAMPP is a comprehensive web server solution that includes Apache, PHP, MySQL, an FTP server, and a mail server, along with management tools like phpMyAdmin Unlike AppServ, XAMPP offers a user-friendly management interface that enables users to easily start or stop server services as needed.

MySQL is the most popular free and open-source database management system, favored by developers for application development due to its high speed, stability, and user-friendly interface It is compatible with multiple operating systems, including Windows, Linux, Mac OS X, and Unix, and offers a robust set of powerful utility functions With its excellent performance and security features, MySQL is ideal for internet-based applications that require efficient database access.

MySQL is used to support PHP, Perl, and many other programming languages, as it stores the information of web pages written in PHP or Perl.

Summary

In this chapter, we explored the fundamental concepts of React, ReactJs, NodeJs, and Python, highlighting their key features Understanding the advantages and disadvantages of each language provides a comprehensive overview, enhancing our knowledge of these essential technologies.

The focus is on the concept of recommender systems and recommender systems include four main categories: Simple Recommenders, Content-based Recommenders, Collaborative filtering Recommenders, and Hybrid Recommenders.

Learn about the tools needed to build this e-commerce system.

SYSTEM ANALYSIS AND DESIGN

Collaborative filtering recommenders

This algorithm predicts a user's preferences for items by analyzing the behaviors of similar users It assesses user similarity based on their interest levels, measured through ratings of previously known items in the system.

Figure 2.9 - Determine the similarity between users

For example: Two users A and B both like Acer laptop products (ie, they both rate these acer laptop products 4 -> 5 stars) Based on B's purchase history, we see that

B bought an LG TV, so it is likely that A also likes this product, from which the system will recommend LG TV to A.

Method one is to determine each user's interest in an item based on the interest of similar users in that item, also known as User-user collaborative filtering.

Method two focuses on identifying item similarities rather than user similarities This approach enables the system to recommend items that are closely related to those the user shows significant interest in.
