Removing elements of string before a specific repeated character in it in javascript

Question

I'm trying to remove from my string all elements before an specific character which is repeated several times in this way:

let string = http://localhost:5000/contact-support

thus I´m just trying to remove everything before the third / having as result:contact_support

for that i just set:

string.substring(string.indexOf('/') + 3);

Bust guess thats not the correct way

Any help about how to improve this in the simplest way please? Thanks in advance!!!

It seems like you want to do some URL parsing here. JS brings the handful URL utility which can help you with this, and other similar tasks.

const myString = 'http://localhost:5000/contact-support';

const pathname = new URL(myString).pathname;

console.log(pathname); // outputs: /contact-support

// then you can also remove the first "/" character with `substring`
const whatIActuallyNeed = pathname.substring(1, pathname.length);

console.log(whatIActuallyNeed); // outputs: contact-support
