Get id from parameters from url using regex [duplicate]

Question

I have a url...

/pensieve/q/22749623

I want to strip this url of everything but the tailing id and store it in a variable...

22749623

I am able to do this using a simple for loop...

var query_id = ''
for(var index = 12; index < query_url.length; index++){
    query_id += query_url[index];
}
var query_id = parseInt(query_id);

How do I do this with Javascript using regex?

I am finding a lot about how to do this in other languages, but not Javascript. I have checked StackOverflow and the rest of the internet to no avail.

if you want to learn how to do it and do it yourself, try this link: w3schools.com/js/js_regexp.asp. Skål — Prefijo Sustantivo

Just try this. (please see this)

var link="/pensieve/q/22749623";
var number = link.match(/\/([^\/]+)\/?$/)[1];
console.log(number);
