JavaScript libraries and frameworks make website and application development easier with wide-ranging features and functionalities — all thanks to JavaScript’s dynamic, flexible, and engaging features. According to a StackOverflow survey from 2020, JavaScript continues to be the most commonly used programming language (for the 8th year), with 67.7% of the respondents using it.
Its versatility favors both back-end and front-end development, in addition to testing them. As a result, you can find many JavaScript libraries and frameworks that serve various purposes. Hence, it can be confusing to developers when choosing the right fit for their project.
But don’t you worry! We’ve compiled a total of 40 JavaScript libraries and frameworks in this article, along with their features, benefits, and use cases. Stay tuned to find out about them and decide which one is suitable for your project.
What Are JavaScript Libraries?
JavaScript libraries contain various functions, methods, or objects to perform practical tasks on a webpage or JS-based application. You can even build a WordPress site with them.
Think of them as a book library where you revisit to read your favorite books. You may be an author and enjoy other authors’ books, get a new perspective or idea, and utilize the same in your life.
Similarly, a JavaScript library has codes or functions that developers can reuse and repurpose. A developer writes these codes, and other developers reuse the same code to perform a certain task, like preparing a slideshow, instead of writing it from scratch. It saves them significant time and effort.
They are precisely the motive behind creating JavaScript libraries, which is why you can find dozens of them for multiple use cases. They not only save you time but also bring simplicity to the entire development process.
How to Use JavaScript Libraries
To use a JavaScript library in your app, add <script> to the <head> element using the src attribute that references the library source path or the URL.
Read the JavaScript library’s documentation you intend to use for more information and follow the steps provided there.
What Are JavaScript Libraries Used For?
As we’ve said, JavaScript libraries are used to perform specific functions. There are around 83 of them, each created to serve some purpose, and we are going to cover some of their usability in this section.
You can use JavaScript libraries for:
-
Data Visualization in Maps and Charts
Data visualization in applications is crucial for users to view the statistics clearly in the admin panel, dashboards, performance metrics, and more.
Presenting these data in charts and maps helps you analyze that data easily and make informed business decisions.
Examples: Chart.js, Apexcharts, Algolia Places
-
DOM Manipulation
Document Object Model (DOM) represents a web page (a document) as objects and nodes that you can modify using JavaScript. You can change its content, style, and structure.
Examples: jQuery, Umbrella JS
-
Data Handling
With the enormous amounts of data that businesses now deal with daily, handling and managing them properly is essential. Using a JavaScript library makes it easier to handle a document following its content while adding more interactivity.
Examples: D3.js
-
Database
Effective database management is necessary to read, create, delete, edit, and sort data. You can also use sophisticated queries, auto-create tables, synchronize and validate data, and much more.
Examples: TaffyDB, ActiveRecord.js
-
Forms
Use JS libraries to simplify form functions, including form validation, synchronization, handling, conditional capabilities, field controls, transforming layouts, and more.
Examples: wForms, LiveValidation, Validanguage, qForms
-
Animations
People love animations, and you can leverage them to make your web page interactive and more engaging. Adding micro-interactions and animations is easy by using JavaScript libraries.
Examples: Anime.js, JSTweener
-
Image Effects
Users can add effects to images and make them stand out using JS libraries. Effects include blurring, lightening, embossing, sharpening, grayscale, saturation, hue, adjusting contrast, flipping, inverting, reflection, and so on.
Examples: ImageFX, Reflection.js
-
Fonts
Users can incorporate any font they wish to make their web page more compelling based on the content type.
Examples: typeface.js
-
Math and String Functions
Adding mathematical expressions, date, time, and strings can be tricky. For example, a date consists of many formats, slashes, and dots to make things complex for you. The same holds when it comes to matrices and vectors.
Use JavaScript libraries to simplify these complexities in addition to manipulating and handling URLs effortlessly.
Examples: Date.js, Sylvester, JavaScript URL Library
-
User Interface and Its Components
You can provide a better user experience via web pages by making them more responsive and dynamic, decreasing the number of DOM operations, boosting page speed, and so forth.
Examples: ReactJS, Glimmer.js

What Are JavaScript Frameworks?
JavaScript frameworks are application frameworks that allow developers to manipulate code to meet their unique requirements.
Web application development is analogous to building a house. You have the option to create everything from scratch with construction materials. But it will consume time and may incur high costs.
But if you use readymade materials such as bricks and assemble them based on the architecture, then construction becomes faster, saving you money and time.
Application development works similarly. Instead of writing every code from scratch, you can use pre-written codes working as building blocks based on the application architecture. Frameworks can adapt to website design more quickly and make it easy to work with JavaScript.

How JavaScript Libraries and Frameworks Work Together
The difference between JavaScript libraries and frameworks lies in its flow of controls. They are just opposite in the flow, or inverted.
In JS libraries, the parent code calls the function that a library offers.
In JS frameworks, the framework itself calls the code and uses it in a specific way. It defines the overall application design.
Simply put, you can think of JavaScript libraries as a particular app function. In contrast, the framework acts like its skeleton, while an API acts as the connector to bring them together.
Commonly, developers start the development process with a JS framework and then complete the app functions with JS libraries and an API’s help.
Summary
JavaScript libraries and frameworks are efficient to accelerate your website or app development process. And as a web developer, using the right one for your project is crucial. If you are a Kinsta customer, you can also take advantage of the code minification feature that is built into the MyKinsta dashboard.
