Overview of Different JavaScript's Libraries-&-Frameworks-&-Middlewares-&-Testing

There are thousands of JavaScript libraries available, each serving different purposes such as DOM manipulation, data visualization, testing, and more. 

Now, lets discuss the different libraries, frameworks and middlewares based on JavaScript Programming/Scripting Language point-wise:

1. Angular: A full-fledged, opinionated framework (uses TypeScript) for building large-scale, enterprise-level single-page applications (SPAs) with built-in features like routing and dependency injection.
2. Vue.js: A progressive framework that is known for its simplicity, ease of integration, and detailed documentation, often used for SPAs and interactive user interfaces.
3. Svelte: A more recent, compiler-based framework that compiles components into highly efficient vanilla JavaScript at build time, resulting in smaller bundle sizes and faster runtime performance without a virtual DOM.
4. Next.js: A React-based full-stack framework that provides features like server-side rendering (SSR) and static site generation (SSG) for performance and SEO optimization, popular for e-commerce and content-heavy sites.
5. Chart.js: A simple yet powerful library for adding various types of charts and graphs to web applications.
6. Ember.js: An opinionated framework that follows the "convention over configuration" principle, providing a robust structure and a complete development solution for ambitious web applications.
7. Nuxt.js: A versatile framework built on Vue.js that enhances it with features like SSR, static generation, and a modular architecture.
8. AXIOS: A promise-based HTTP client for making API requests, widely used in modern JavaScript applications.
9. Express.js: A minimalist and flexible back-end web application framework for Node.js, providing a robust set of features for building web servers and APIs, with extensive middleware support.
10. React.js: A popular library for building user interfaces with a component-based architecture and a virtual DOM for efficient updates.
11. Moment.js: Is a legacy JavaScript library designed to simplify the parsing, validation, manipulation, and display of dates and times.
12. jQuery: A classic, lightweight library that simplifies HTML DOM manipulation, event handling, animations, and AJAX calls, and works across multiple browsers.
13. D3.js: (Data-Driven Documents) A library for creating dynamic and interactive data visualizations (charts, graphs, etc.) by binding data to the DOM.
14. Lodash: Provides utility functions for common programming tasks, such as working with arrays, objects, and strings, making code cleaner and more concise.
15. Three.js: A library used to create and display animated 3D computer graphics in a web browser using WebGL.
16. Socket.IO: Enables real-time, event-based, two-way communication between the client (browser) and the server using WebSockets.
17. BODY-PARSER: Parses incoming HTTP request bodies, which is useful for handling form data or JSON payloads. Express.js now includes built-in versions of this functionality (express.json(), express.urlencoded()).
18. MORGAN: An HTTP request logger middleware, used for logging request details in development and production environments.
19. HELMET: A collection of middleware functions that help secure Node.js applications by setting various security-related HTTP headers to mitigate common vulnerabilities like XSS and CSRF.
20. CORS: Enables Cross-Origin Resource Sharing (CORS) with various options, allowing the server to specify which origins are permitted to access its resources.
21. PASSPORT: A popular authentication middleware that offers a flexible, modular architecture to implement various authentication strategies (local, OAuth, JWT, etc.).
22. KOA: Developed by the team behind Express, Koa is a lighter-weight Node.js middleware framework that uses async functions to simplify error handling and improve code readability.
23. NESTJS: A progressive Node.js framework for building scalable, enterprise-level server-side applications, utilizing TypeScript and a modular architecture inspired by Angular.
24. REDUX: While primarily used as a state management library with React, its core principles can be applied across different frameworks (with relevant bindings) to manage application state in a predictable way using middleware to handle side effects.
25. SAILSJS: A real-time MVC framework built on Node.js and Express that simplifies building APIs and supports WebSockets for live data updates.
26. JEST: A delightful JavaScript testing framework with a focus on simplicity.
27. MOCHA: A feature-rich testing framework for Node.js and the browser, making asynchronous testing simple.
28. JASMINE: A Behavior Driven Development (BDD) testing framework for JavaScript. 

Utility and Functionality

These libraries provide helper functions for common tasks, data handling, and asynchronous operations. 

• Lodash / Underscore.js: Provide utility functions for common programming tasks, such as array manipulation, object handling, and functional programming helpers.
• Axios / SuperAgent: Libraries used for making HTTP requests (Ajax) from the browser or Node.js, offering a simpler API than the built-in fetch or XMLHttpRequest. 

Data Visualization and Graphics

These libraries are used to create interactive charts, graphs, and 3D scenes. 

• D3.js (Data-Driven Documents): A powerful library for manipulating documents based on data, enabling the creation of custom, dynamic data visualizations in HTML, SVG, and CSS.
• Chart.js: A simple and flexible library for adding charts and graphs to web pages.
• Three.js: A library that simplifies the use of WebGL for creating animated 3D computer graphics in a web browser. 

UI and Frontend Development

While some of these are technically classified as frameworks because they dictate application architecture, they are often used as UI building libraries. 

• React.js: A library for building user interfaces using a component-based approach and a virtual DOM.
• Vue.js: A progressive framework for building user interfaces, known for its gentle learning curve and flexibility.
• Angular: A comprehensive, TypeScript-based framework (not just a library) maintained by Google, suitable for building complex enterprise single-page applications.
• Bootstrap: A popular library/toolkit for designing responsive and mobile-first user interfaces using pre-built components and utility classes. 

DOM (Document Object Model) Manipulation 

These libraries help simplify interaction with the elements of a web page. 

• jQuery: A fast, small, and feature-rich library that simplifies tasks like HTML document traversal and manipulation, event handling, and Ajax.
• Dojo Toolkit: One of the older, still relevant toolkits for web application implementation and dynamic content, which also handles DOM and Ajax requests.
