JavaScript Snippets: Augmented Native Objects

sandbox.js

String.augmentedProperties = [];

if (!String.prototype.camelize) {
  String.prototype.camelize = function() {
    return this.replace(/(\s)([a-zA-Z])/g, function(str, p1, p2) {
      return p2.toUpperCase();
    });
  };
  String.augmentedProperties.push("camelize");
}

if (!String.prototype.reverse) {
  String.prototype.reverse = function() {
    return this.split("").reverse().join("");
  };
  String.augmentedProperties.push("reverse");
}

if (!String.prototype.trim) {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, "");
  };
  String.augmentedProperties.push("trim");
}


Array.augmentedProperties = [];

if (!Array.prototype.inArray) {
  Array.prototype.inArray = function(needle) {
    for(var i=0; i<this.length; i++) {
      if (this[i] == needle) {
        return true;
      }
    }
    return false;
  };
  Array.augmentedProperties.push("inArray");
}

Here a version without regex, just in case. :) Then again, regex will be faster here...

String.prototype.camelize = function() {
  return this.split(" ").map( function(w) { return w.substr(0, 1).toUpperCase() + w.substr(1); } ).join("");
}

But why do you want to return the empty string, I think that's useless here:

String.prototype.camelize = function() {
  return this.replace(/(\s)([a-zA-Z])/g, function(str, p1, p2) {
    return p2.toUpperCase();
  });
};

Nice addition, thanks! I updated the camelize method.
