> Strip comments from JSON. Lets you use comments in your JSON files!

This is now possible:

```js
{
	// Rainbows
	"unicorn": /* ❤ */ "cake"
}
```

It will replace single-line comments `//` and multi-line comments `/**/` with whitespace. This allows JSON error positions to remain as close as possible to the original source.

Also available as a [Gulp](https://github.com/sindresorhus/gulp-strip-json-comments)/[Grunt](https://github.com/sindresorhus/grunt-strip-json-comments)/[Broccoli](https://github.com/sindresorhus/broccoli-strip-json-comments) plugin.

npm install strip-json-comments

const json = `{
	// Rainbows
	"unicorn": /* ❤ */ "cake"
}`;

//=> {unicorn: 'cake'}
```
