##Introduction
JavaScript libraries have been changing the way we write JavaScript and have helped us in accomplishing our goals easily without the hassle of reinventing the wheel over and over again. That’s why JavaScript libraries are one of the first things that any developer should be aware of when starting out in this industry. Every year, new libraries are developed, old ones are abandoned, and all existing ones need to be updated with the latest advancements made by developers around the world.
But what’s so special about these libraries that they deserve special attention? These libraries promise to make coding faster, easier, and overall more enjoyable. I recommend taking some time out in 2022 to take them for a spin!
Here’s a list of the ones you should try out in 2022 if you haven’t already started to work with them. They may not be the most popular right now, but I predict they will be in three years!
