Required a solution in searching string in NodeJs

Question

I have a string "platform:17.01.02" and I want to search for "17.01.02" which I'm giving through a variable.

a = "platform:17.01.02"
b = "17.01.02" (has to taken from user)

a.search(/b/)

The above statement search for "b" and not for variable value "b". Can any one help how can i search that?

`b` doesn't look like a regex, so you should not use `search` — Bergi, Mar 21 '17 at 11:28
You are looking for [`a.indexOf(b)`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/indexOf) — Bergi, Mar 21 '17 at 11:40

Try this:

var a = "platform:17.01.02";
var b = "17.01.02";

console.log(a.search(new RegExp(b))); //9

If you just want to know if a contains b, use:

a.indexOf(b) >= 0

that will yield unexpected results when the user accidentally types in regex metacharacters – Bergi Mar 21 '17 at 11:29
