The compiler for writing next generation JavaScript.

Babel is community-driven and thus mostly maintained by a group ofvolunteers. It has a lot ofcompanies 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 developer time on the project. (Message us onTwitter orSlack)
• Giving funds by becoming a backer/sponsor on OpenCollective

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){returnn+1;});
