JavaScript Libraries in 2022

The 5 Most Popular JavaScript Libraries in 2022

1. React

React is a free open-source, front-end JavaScript library for building user interfaces. React was created by Meta (formerly Facebook) in 2003 and was first used publicly on Facebook’s News Feed in 2011. It became open-sourced, and therefore available to developers, in May 2013. Since that time, it has become incredibly popular, overtaking jQuery as a programmers most beloved JavaScript library. It is used by tech giants such as Facebook, Instagram, Paypal, Netflix, and Codecademy.


  • Virtual DOM: React creates an in-memory data-structure cache. When we create a DOM object, a virtual DOM object, or clone, is created. Because of its memory, programmers don’t have to program every detail into every page. Multiple programmers can write code without causing any major changes to the project's roots. This saves developers time and reduces labor cost while creating a fast-running product with a smaller-than-usual footprint.
  • Native Development: Because React is both a library and a framework, it can be used for native development. This results in faster performance, greater data protection, and fewer bugs to work out. Also, because the two were made for each other, together they can optimize all of the tools created for both.
  • Unidirectional Data Flow: Data flow in React is organized in a top-down fashion. This makes applications created with React faster, more organized, less error-prone, and easier to debug.

2. React Native

React Native isn't a JavaScript library, rather, it is a framework worthy of addressing along with React. It was open-sourced in March 2015 and allows native Android, Android TV, iOS, macOS, tvOS, Web, Windows, UWP, and even VR development with React. This framework saves time, creates high-performance applications, is collaborative, and can be used to create multiple applications in their entirety. What exactly makes React Native unique?


  • Reusable Code:  React Native allows developers to reuse up to 90% of their code. This is a major time saver, as we are now able to write code and use much of that same code for web, iOS, and Android interfaces instead of creating three separate applications from scratch.
  • Native Mobile UI: This feature allows us to create a faster, smoother web application.
  • Modular Interface: Developers can work remotely with each other for the entirety of the project. We share our work, make updates, and test functionality all through one mutually understood framework.
  • Holistic: React Native is used to build native mobile applications as a stand-alone framework. This is different from other frameworks such as React.js, which can be used to build the majority of an application, but requires additional libraries to complete a project.
By using React and React Native, we create user-interfaces which are sophisticated, yet easy to understand for both the user and the development team. The React framework and its accompanying library have become exponentially more popular within the last year and, given its straightforward integration, will continue to be an exceptional software tool for many years to come.

3. Node.js

Node.js was created in May 2009 and adapted for use on Windows computers in 2011. It is technically a back-end JavaScript runtime environment, which is more of an interpreter, than a library. It executes JavaScript code outside of a web browser in tools, such as a computer’s command prompt. This allows developers to develop web pages server-side before uploading them to the web. Node.js allows applications to be developed in one language for both server and client-side scripts. Node is great for API (application programming interface) development. We use it to develop networking tools and web servers. This runtime environment is utilized by corporate users such as Netflix, Paypal, Walmart, Amazon, LinkedIn, Microsoft, and Groupon.


  • Event-Driven Architecture: Because of its architecture, Node.js is capable of asynchronous input and output processing. This means the server doesn’t have to wait for the API to come back with data before proceeding onto its next task, making applications developed with Node.js very fast. This feature also makes applications developed with Node.js incredibly scalable, meaning they are able to handle an increase in users and data. This is important for allowing efficient accommodation of growth. All web applications should be designed with scalability in mind.
  • Node Package Manager: The NPM is a directory of over one million JavaScript libraries which allows Node.js to fully support a huge number of helpful development tools such as Express, SQL databases, and even Lodash. The manager itself is designed for smoother installation, updating, and uninstallation of these packages, making it easier for developers to share source code. This allows development teams to work in JavaScript for the entire project.
  • Single-Threaded Event Loop Model: Node.js differs from other clients such as ASP.NET, HTML, Ajax, and jQuery in that it is single-threaded, rather than multi-threaded. Because of this, it can handle a greater number of concurrent requests. This makes it a fantastic choice for an application that has a lot of web traffic, or needs to do many tasks simultaneously. It also means that applications built using Node.js use less memory and fewer resources than they would being built with a different software.

By using Node.js, we develop programs which are fast, incredibly scalable, and capable of many concurrent requests. The Node.js JavaScript runtime environment has gained popularity in the last four years and is continuing to grow with increased momentum. We are impressed with Node.js for its flexibility, ease of efficient program testing, and creative potential.

4. JQuery

Released in 2006, jQuery is a long-standing, popular JavaScript library known to all JavaScript developers. It is used to create dynamic web pages quickly, even those with a lot of features. A complete web application cannot be completed with jQuery alone, which is why it is commonly paired with jQuery UI. jQuery has been continually updated since its initial release, and while it is over 15 years old, it is still significantly more popular than newer alternatives such as Vue.js, D3.js, EXT.js, and Svelte. jQuery is helpful for HTML traversal, event handling, basic DOM manipulation, and animation. In 2022, 78.3% of the 10 million most popular websites used jQuery, this is up 5% from three years prior.

5. D3.js

D3.js (short for Data-Driven Documents) is a JavaScript library released in 2011 with web design in mind. The project was expanded in 2016 to evolve from a single library into a series of modular libraries. It utilizes HTML, SVG, and CSS to create interactive graphics from data. It is unique from its predecessors in the fact that it does not require Java or Flash plug-ins in order to render images. With D3.js web designers or developers can create and style objects, or generate charts, graphs, and diagrams. D3.js is commonly used for data-driven websites which require frequent updating such as news sites. It is also used to create content for academic web programs, websites about the stock market, and calendar or map widgets. We appreciate D3.js for its unique ability to present content in a visually interactive and organized manner.

Are We Missing Something?

As a simple definition, libraries are snippets of pre-built code that are used and reused to build a web application.  Libraries provide building blocks. Frameworks, on the other hand, are more like a blueprint or frame of a project. JavaScript Frameworks are a collection of pre-built code. Here is our research on cutting edge JavaScript frameworks.
