The compiler for writing next generation JavaScript.
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:
- Giving funds by becoming a backer/sponsor on OpenCollective
- Giving developer time on the project. (Message us on Twitter or Slack)
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 and follow us at @babeljs.
