Supporting Babel

Backers on Open Collective Sponsors on Open Collective Business Strategy Status

Babel is community-driven and thus mostly maintained by a group of volunteers. It has a lot of companies and projects using it but almost no sponsors/people funded to work on it. If you'd like to help maintain the future of the project, please consider:

Intro

Babel is a tool that helps you write code in the latest version of JavaScript. When your supported environments don't support certain features natively, Babel will help you compile those features down to a supported version.

In

// ES2015 arrow function
[1, 2, 3].map((n) => n + 1);

Out

[1, 2, 3].map(function(n) {
  return n + 1;
});

Try it out at our REPL.

FAQ

Who maintains Babel?

Mostly a handful of volunteers! Please check out our team page!
