science-halt
============

usage
-----

```js
var scihalt = require('science-halt');

scihalt(function(){
// do something when ESC is pressed
})
``

rationale
---------

This is a stupid module. Everytime I make a game loop, I do something like this:

``js
var last = Date.now()
, running = true;

(function anim() {
if (running) requestAnimationFrame(anim);
var now = Date.now();
doUpdate(now - last);
last = now;
}());

document.addEventListener('keydown', function(e) {
if (e.which == 27) {
running = false;
console.log('HALT IN THE NAME OF SCIENCE!');
}
})
``

This module takes care of the keybinding for halting... because apparently I find 27 a really hard number to remember. The above example becomes:

``js
var scihalt = require('science-halt');

var last = Date.now()
, running = true;

(function anim() {
if (running) requestAnimationFrame(anim);
var now = Date.now();
doUpdate(now - last);
last = now;
}());

scihalt(function() { running = false; })
```
