Array Class

The array class is used for storing values in an ordered list. You can add, read and delete values from it. Each item is stored against an index value, which is a positive whole number.

// new Array examples
ns = [ 1, 2, 3 ]
ns = new Array()

// adding values
ns.add( 5 )
ns.push( 2 )
ns.unshift( 3 )

// iterating
ns.each() do |n|
    // code here
end

// iterating with key
ns.each() do |i, n|
    // code here
end

Note that if you set a value outside of the size of the array, then all of the empty values will be padded with 'null'.
