regex URL extract slash

Question

I need to extract the middle number from this using regex:

/166012342170/934760332134/794294808150/2436280815794/

Needed output: 934760332134

I tried using this: (?:.+?/){2}

I am new to regex :(

Or use a capturing group `^/\d+/(\d+)` https://regex101.com/r/dzMrXh/1 — The fourth bird, Feb 20 '19 at 21:01

If this is actually a URL, you can use [this](https://stackoverflow.com/a/24006120/2928853) answer, extract `pathname` from the URL, and then split on `/` character. No need for a complicated regex really. — jrook, Feb 20 '19 at 21:23
In JS, you may even use `s.split("/")[2]`. Or, if you still want regex, `var m = s.match(/^\/[^\/]+\/([^\/]+)/); if (m) console.log(m[1]);` — Wiktor Stribiżew, Feb 20 '19 at 21:23

In JS, you may simply split the string with / char:

console.log('/166012342170/934760332134/794294808150/2436280815794/'.split('/')[2])

If you plan to use regex you may use

var s = '/166012342170/934760332134/794294808150/2436280815794/';
var m = s.match(/^\/[^\/]+\/([^\/]+)/); 
if (m) {
  console.log(m[1]);
}

To get that second number, the regex would be

(?:\/([0-9]+)){2}

which gives 934760332134 from the line below,

/166012342170/934760332134/794294808150/2436280815794

Try it on here.
