Choosing the right JavaScript library is crucial, especially early in a project. Otherwise, there is a big chance you spend a lot of time cleaning up the mess later. But how to know which one is best?

In web development, there isn't always a single "best choice." However, there are usually better options than others, and considering the following factors might assist you in making the right decision.
## Widespread usage
Libraries and frameworks that are widely used provide access to a lot of tutorials, courses and discussions about best practices, how-tos, and blogs. Widely used libraries and frameworks would also make it easier to find developers with the necessary experience. In addition, many developers would be eager to work for your business and gain experience.
## Detailed documentation
A good documentation makes the library easy to use and helps avoid wasting time. Libraries with straightforward and understandable APIs can get by with little documentation. But complex libraries with difficult concepts require in-depth explanations, examples, and tutorials. You can get started more quickly if you refer to the documentation, which may even include sample code. 
## Development activity
Active development ensures that any bugs are immediately rectified, and new functionality is added to projects. Check the date in their changelog to see how recently the library was updated. If the library is published in an open source repository like GitHub and there isn't a changelog, you can look for the most recent commit date.
## Active community
A big user base may increase the likelihood that bugs will be found quickly and frequently. More external contributors to the library or framework may result from an active community. They may assist in delivering features that would not normally be on the author's plan. It could also mean the addition of more courses, videos, courses, manuals, and tutorials on the relevant library or framework.
## Browser support
Verify that a library supports each of the browsers you choose. Many libraries these days purposely don't support earlier browsers’ versions, which your website may need to support, because they are exclusively meant to be lightweight. If the UI component from a library is ever used by your users on a mobile browser, it needs to function properly for them there.
