Remove phrase from string using regex and a variable

Question

Can anyone help me with this regex I can't get the regex to match. I'm trying to remove the phrases that match from the string

let url = 'en-gb/products/product-category/186/product-type/2';
let word = "product-category";
let regex = new RegExp("\/" + word + "\/\d+", "g");
let output = url.replace(regex, '');
//desired output = 'en-gb/products/product-type/2'
console.log(output);

You have an extra `/` at the beginning of the regexp, so it's looking for `//product-category`. — Barmar, May 06 '21 at 16:00
There's also no need to escape `/` when you're creating the regexp with `new RegExp` — Barmar, May 06 '21 at 16:01
That was a mistake copying that's not the problem. I'm not getting the output like that just the original string — Jordan, May 06 '21 at 16:02

You were close, you need to do it like so:

let url = 'en-gb/products/product-category/186/product-type/2';
let word = 'product-category';
let regex = new RegExp(word + '/\\d+/', 'g');
let output = url.replace(regex, '');
//desired output = 'en-gb/products/product-type/2'
console.log(output);

Also please try to be consistent with either double or single quotes.
