Some nice javascript string manipulations

gistfile1.js

/**
 * Takes a string and capitalizes the first letter.
 *
 * @example
 *   "this is an all lower-case string".capitalize();
 *   // => "This is an all lower-case string"
 *
 * @return String
 **/
String.prototype.capitalize = function(){
  return this.charAt(0).toUpperCase() + this.slice(1);
};

/**
 * Splits on non-word characters, then joins the pieces back together.
 *
 * NOTE: this won't do any sort of capitalization, in order to avoid some
 * weirdness (at least, unpredictable weirdness).
 *
 * @example
 *   "Multiple/Categorical/Choices".classify();
 *   // => "MultipleCategoricalChoices"
 *
 *   "Mike's Bar & Grill".classify();
 *   // => MikesBarGrill"
 *
 *  "Won't capitalize Words".classify();
 *  // => "WontcapitalizeWords" -- if we capitalized words, it'd look like this: "WonTCapitalizeWords"
 *
 * @return String
 **/
String.prototype.classify = function(){
  return this.split(/\W/).join("");
};
