25 Best JavaScript Libraries To Find In 2024

JavaScript, or JS, is unarguably the most used programming language for creating dynamic and interactive web applications. JavaScript, also along with CSS and HTML, form the basis of the majority of web platforms. JS essentially lets you add interactive elements to your web pages – for example, buttons, animations, interactive maps and charts. However, creating an enterprise-grade web app with lots of interactive elements involves complex programming tasks. This is where you can use JavaScript libraries to make typical programming tasks easier and speed up the web development process.

JavaScript libraries also come with pre-written, reusable JavaScript code or functions that web developers can use to add new features to their web apps. In other words, when you’re using a JS library, you don’t have to write certain repetitive code snippets again and again. JS libraries also help reduce coding errors and bugs and make your apps faster. All in all, there are several JavaScript libraries available today, and deciding which JavaScript library you should use for your next web development project can be challenging. That’s why we’ve curated a list of the best JavaScript libraries to help you choose the right one for your needs.
