String Prototype Extensions - Post Your Best!

I couldn't find a single thread with the creme de la creme of String prototype extension methods, so I figured I'd start one. Here we go!

String.prototype.lTrim = function () {
return this.replace(/^s+/gm, "");
}

String.prototype.rTrim = function () {
return this.replace(/s+$/gm, "");
}

String.prototype.trim = function () {
return this.rTrim().lTrim();
}Obviously, this one's easy to understand. I'm using multi-line mode so as only to get rid of spaces and tabs before and after words. Single-line mode would replace any newline/carriage return characters as well.


String.prototype.capitalize = function () {
return this.replace(/[a-z]/g, function (str, n) { return str.toUpperCase(); });
}

String.prototype.toCamelCase = function () {
return this.replace(/s[a-z]/g, function (str, n) { return str.toUpperCase(); });
}

String.prototype.unCamelCase = function () {
return this.replace(/[A-Z]/g, function (str, n) { return " " + str.toUpperCase(); });
}This is something I needed today, to turn a camelCased variable value into its Header Format. While I was at it, I wrote the un-do-er.
