How to preserve dot using split and negative lookahead

Question

I would like preserve dots using split function.

string exemple :

var str = "oqisjdf qosdifjq. fqs and the, fo. osidfo tchim cth."

If I use str.split('.'), I'll obtain :

["oqisjdf qosdifjq", " fqs and the, fo", " osidfo tchim cth", ""]

but this is what I need :

["oqisjdf qosdifjq.", " fqs and the, fo.", " osidfo tchim cth."]

You could split by a positive lookbehind.

var string = "oqisjdf qosdifjq. fqs and the, fo. osidfo tchim cth.",
    array = string.split(/(?<=\.)/);

console.log(array);
