JavaScript equivalent for PHP preg_replace

javascripts string.replace function also takes a regular expression:

"test    test  test    test".replace(/ +/,'-');

In JavaScript, you would write it as:

result = subject.replace(/ +/g, "-");

By the way, are you sure you've posted the right PHP code? It would rather be:

$result = preg_replace('/ +/', '-', $str);

var text = 'test   test   test test';
var fixed = text.replace(/\s+/g, '-');
