**6to5** turns ES6+ code into vanilla ES5, so you can use next generation features **today.**

 - **Readable** - formatting is retained if possible so your generated code is as similar as possible.
 - **Extensible** - with a large range of [plugins](plugins.md) and **browser support**.
 - **Lossless** - **source map support** so you can debug your compiled code with ease.
 - **Compact** - maps directly to the equivalent ES5 with **no runtime**[\*](caveats.md).

## Installation

It's as easy as:

    $ npm install -g 6to5

## Usage

Once you've installed 6to5, there are multiple paths you can take depending on
how you want to use it.

6to5 will simply compile your ES6+ script to ES5 if you pass it as an argument
to the command-line tool `6to5`:

    $ 6to5 script.js

If you have a file written using ES6+ and you just want to run it, `6to5-node`
has you covered:

    $ 6to5-node script.js

And it doesn't end here! To see all the ways you can use 6to5, check out the
[Usage](http://6to5.github.io/usage.html) page.
