Babel

What do you like best?

Easy to implement and use in any project, compiles next-gen JavaScript code into ES5 for use in older browsers and polyfills most modern features to make them accessible to a wide range of developers and the projects they work on.

What do you dislike?

Adds additional bloat to the bundle-size of JavaScript applications - not a big downside for me, but something to be aware of.

Recommendations to others considering the product:

Babel is a must-have tool for any modern JavaScript developer.

What problems are you solving with the product? What benefits have you realized?

Writing the most modern JavaScript code possible while keeping applications compatible down to Internet Explorer 11 and legacy Edge browsers.
