Regex to split camel case

Question

I have a regular expression in JavaScript to split my camel case string at the upper-case letters using the following code (which I subsequently got from here):

Answer 1

a = 'threeBlindMice'
a.match(/[A-Z]?[a-z]+/g) // [ 'three', 'Blind', 'Mice' ]

is the simplest way I've found, for simple camel/titlecase splitting.
