utility $H
$H([obj]) → Hash
Creates a Hash
(which is synonymous to "map" or "associative array"
for our purposes). A convenience wrapper around the Hash
constructor, with a safeguard
that lets you pass an existing Hash
object and get it back untouched (instead of
uselessly cloning it).
The $H
function is the shorter way to obtain a hash (prior to 1.5 final, it was
the only proper way of getting one).
Example
var h = $H({name: 'John', age: 26, country: 'Australia'});
// Equivalent to:
var h = new Hash({name: 'John', age: 26, country: 'Australia'});
// Can then be accessed the classic Hash way
h.get('country');
// -> 'Australia'
