Javascript split string by another string and include that another string that was used to split it into result

Question

If I have this string: "MyStringToForSplitting" and I want to split it by this word "ring". If I do this: "MyStringToForSplitting".split('ring') I will get array that contains this elements:

MyS
ToForSplitting

I can't figure out best way to split it and include 'ring' in resulting array like this:

1.MyS

2.ring

3.ForSplitting

Sorry for duplication. Didn't find that one... – Vlado Pandžić Jul 14 '17 at 18:02 — Vlado Pandžić, Jul 14 '17 at 18:02

You can use regex and capture the split pattern:

console.log("MyStringToForSplitting".split(/(ring)/));

var s = "ring";
var p = new RegExp("(" + s + ")")
console.log("MyStringForSplitting".split(p))

What is ring is variable not hardcoded string? – Vlado Pandžić Jul 14 '17 at 18:11
You can construct the regular expression from the string variable and then use it for split. See the update. – Psidom Jul 14 '17 at 18:16

And if you want to ignore casing then new RegExp("(" + s + ")","i") can be used – Vlado Pandžić Jul 14 '17 at 18:36
