Capitalize: lowercase the rest of the string?

[proustibat]

We could maybe consider that if we call capitalize on a string, we expect the first letter to be uppercase but the rest to be in lowercase ?
I suggest we could add it as follows:
var capitalize = str => str[0].toUpperCase() + str.slice(1).toLowerCase();

or with a default option as follows:
var capitalize = (str, lowerRest=true) => str[0].toUpperCase() + (lowerRest ? str.slice(1).toLowerCase() : str.slice(1));

Good idea! I prefer the default option idea, as it is more like progressive enhancement for the snippet. I would also argue that lowerRest should default to false, to avoid confusion, but I might be in the minority here.

Just added this to the existing snippet. Thanks for the idea!
