String.camelize

camelize.js

// I thought I needed it, but I didn't need it anymore,
// but I already implemented it. So, here we go, if you
// ever would need a Javascript camelize implementation
// you can freely use this :-).

jQuery.extend (String.prototype, {
  camelize: function () {
    return s.replace(/(?:^|[-_])(\w)/g, function (stripped, letter) {
        return letter ? letter.toUpperCase () : '';
    }).replace(/(^\w)/, function(letter) { return letter.toLowerCase()});
  }
});

This reviews correctly lowers the very first letter (otherwise we have PascalCase, not camelCase).
