Using Javascript RegExp to modifiy a link-CodePudding

I need your help and I'm a little bit lost. So I want to obtain "https://cloud.send.cm/i/00344/zofwynu8cxc7.jpg" from "https://send.cm/zofwynu8cxc7.html" . As you can see "zofwynu8cxc7" is the same in both links, so basically I need to copy this photo's id to the other link. This should be possibly using regexp in js, but I'm not quite sure how. Thank you

Here's the new URL("") code:
not sure if path.slice() can be done with URL()

let url = new URL("https://send.cm/zofwynu8cxc7.html")
let path = url.pathname                                 // /zofwynu8cxc7.html
path = path.slice(0, path.length - 5)                   // /zofwynu8cxc7

console.log("https://cloud.send.cm/i/00344"   path   ".jpg")
