What I like best about Express.js is the documentation around it. It's also easy to scaffold an application on Express.js and begin to write apis. Express.js has a vibrant and active community around it as well

It is simple to understand, has plenty of useful features, has great documentation, and is trendy; therefore, it is easy to find someone with similar problems you might face to help you solve them.

Easy to understand and learn framework,it allows us to do whatever we want instead of providing any inbuilt syntax unlike other framework and also routing is easy
