Babel是编写下一代JavaScript的编译器。Babel是一种工具链，主要用于将ECMAScript 2015+代码转换为当前和旧版浏览器或环境中的向后兼容版本的JavaScript。

Babel是一个社区驱动的工具，可帮助您在最新版本的JavaScript中编写代码。

以下是Babel可以为您做的主要事情：

  • 转换语法
  • 目标环境中缺少的Polyfill功能（通过@ babel /polyfill）
  • 源代码转换（codemods）
  • 和更多！ （看看这些视频的灵感）

当您支持的环境本身不支持某些功能时，Babel将帮助您将这些功能编译为受支持的版本。

In

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

Out

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

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.
