Re^3: Five Ways to Reverse a String of Words (C#, Perl 5, Perl6, Ruby, Haskell)

Actually that doesn't work correctly in FF or Safari on OS X. It still has several empty strings filling up the array. They become more evident if you do this:

"  one   two three four    ".split(/ /).reverse().join("|")

which gives you "||||four|three|two|||one||".

Interesting... It works fine in EcmaScript. Or at least Jscript. :-) So how about `" one two three four ".split(/ +/).reverse().join(" ")` [download] We're building the house of the future together.	[reply] [d/l]

Trimming the string is still necessary in order to comply with the specs. Yes, very boring ;-) `function reverseWords(str) { return str.replace(/^\s+/,'').replace(/\s+$/,'').split(/\s+/).revers +e().join(' '); };` [download] -- AltBlue.	[reply] [d/l]
