utility $w
$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 :-)
Examples
$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);
