Split JS string via Regex?

Question

I have MMYY pattern ( credit card expiry)

I need to analyze each section (01 and 14) : So I tried :

'0114'.split(/\d{2}/i) //  ["", "", ""]

It actually see 2 digits as a separators and hence I get nothing.

However , I've managed to do it with :

'0114'.match(/\d{2}/ig) //["01", "14"]

But I wonder about split.

Can I do it also with split ?

Answer 1

For example:

"1234".split(/(?=..$)/) => ["12", "34"]

A generic solution for strings of arbitrary length appears to be impossible, the best we can get is something like:

str.split(str.length & 1 ? /(?=(?:..)*.$)/ : /(?=(?:..)+$)/)
