## Info
A highly experimental set of prototype extensions for native types in ES5 JavaScript.
## What are rubyisms?
Rubyisms are methods that are easy on the eyes.
Here's one in action.
```JavaScript
(5).times(function (n) {
console.log('Yo.');
});
```
Sweet, huh?
Rubyisms are a little slice of coding happiness.
