Hey, javascript! Are you fucking kidding me?!

int.py

In [1]: map(int, ('00', '01', '02', '03', '04', '05', '06', '07', '08', '09'))
Out[1]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Integer.rb

>> ['00', '01', '02', '03', '04', '05', '06', '07', '08', '09'].map! {|x| Integer(x)}
ArgumentError: invalid value for Integer: "08"
	from (irb):1:in `Integer'
	from (irb):1
	from (irb):1:in `map!'
	from (irb):1
>> ['00', '01', '02', '03', '04', '05', '06', '07', '08', '09'].map! {|x| Integer(Float(x))}
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

intval.php

php > print_r(array_map(intval, array('00', '01', '02', '03', '04', '05', '06', '07', '08', '09')));
Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 4
    [5] => 5
    [6] => 6
    [7] => 7
    [8] => 8
    [9] => 9
)

parseInt.js

> ["00", "01", "02", "03", "04", "05", "06", "07", "08", "09"].map(parseInt);
[0, NaN, 0, 0, 0, 0, 0, 0, 0, 0]
> ["00", "01", "02", "03", "04", "05", "06", "07", "08", "09"].map(function(item) { return parseInt(item); });
[0, 1, 2, 3, 4, 5, 6, 7, 0, 0]
> ["00", "01", "02", "03", "04", "05", "06", "07", "08", "09"].map(function(item) { return parseInt(parseFloat(item)); });
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

That's totally predictable and complies to parseInt specs :)
