# fast.js
[](https://travis-ci.org/codemix/fast.js)
Faster user-land reimplementations for several common builtin native JavaScript functions.
> Note: fast.js is very young and in active development. The current version is optimised for V8 (chrome / node.js) and may not perform well in other JavaScript engines, so you may not want to use it in the browser at this point. Please read the [caveats section](#caveats) before using fast.js.
## What?
Fast.js is a collection of micro-optimisations aimed at making writing very fast JavaScript programs easier. It includes fast replacements for several built-in native methods such as `.forEach`, `.map`, `.reduce` etc, as well as common utility methods such as `.clone`.
## Installation
Via [npm](https://npmjs.org/package/fast.js):
```
