$w(String) → Array

Splits a string into an Array, treating all whitespace as delimiters. Equivalent to Ruby's %w{foo bar} or Perl's qw(foo bar).

This is one of those life-savers for people who just hate commas in literal arrays :-)


$w('apples bananas kiwis')
// -> ['apples', 'bananas', 'kiwis']

This can slightly shorten code when writing simple iterations:

$w('apples bananas kiwis').each(function(fruit){
  var message = 'I like ' + fruit
  // do something with the message

This also becomes sweet when combined with Element functions:

$w('ads navbar funkyLinks').each(Element.hide);
