Extending JavaScript – The Right Way | Websanova: "However, this was wreaking havoc on a plugin I had written that happened to be iterating through each character in a string. By simply changing the enumerable property to false we can avoid this problem which can be done by using the defineProperty method like so:
if(!String.prototype.capitalize)
{
Object.defineProperty(String.prototype, 'capitalize',
{
value: function()
{
return this.slice(0,1).toUpperCase() + this.slice(1).toLowerCase();
},
enumerable: false
});
}"
