It helps us make websites interactive and user-friendly. However, it can sometimes be a bit complicated. That’s where JavaScript libraries come to the rescue. One powerful example is Sencha Ext JS.

Think of JavaScript libraries as ready-made toolkits. These toolkits help developers build websites faster and with less hassle. They contain chunks of code that solve common web development problems. For example, creating buttons, forms, and interactive features using Ext JS. This means developers don’t have to start from scratch every time they build a new website.

In this article, we’re going to introduce you to 10 essential JavaScript libraries. These libraries make the development process much smoother. They act like shortcuts to help developers focus on the unique parts of their projects.

We’ll explore libraries like Sencha, React, Vue JS, D3.JS, Bootstrap, Lodash, Axios, Three.JS, and Redux. By the end, you’ll understand what each library does and how they can make your web development journey easier and more efficient. So, let’s get started and discover why these JavaScript libraries are a must-know for developers!

Why Do We Need JavaScript Libraries?

JavaScript libraries help us in the journey of web development. These libraries make our work easy by providing us with code building blocks. Hence, we don’t need to build everything from scratch.

Building websites from the ground up using only basic JavaScript can be like reinventing our project every time. It can consume a lot of time and can lead to mistakes.

On the other hand, JavaScript libraries step in to save the day.

They’ve got ready-made bits of code for common tasks. For example, you can easily create interactive forms or cool animations. The best part is that many smart developers have tested these libraries. So, they work well and are free to use. These can help us build websites much faster and with fewer errors.

Suppose we want to add a fancy image slider to our newly created website. Instead of writing all the code to make it work, we can just choose a JavaScript library.

JavaScript libraries speed up development and make it easier to maintain your site. When updates or bug fixes are needed, you can rely on the library’s community of developers to provide them. So, these libraries are like your trusty toolset, making web development smoother and more efficient.
