Answer 1

You could split by slashes, pop off the last 988 that you don't want, then join again:

const url = '131/131/980/981/982/983/984/985/986/987/988';
const splits = url.split('/');
splits.pop();
const fixedUrl = splits.join('/');
console.log(fixedUrl);

Another option would be to use a regular expression:

const url = '131/131/980/981/982/983/984/985/986/987/988';
const fixedUrl = url.match(/\d+(?:\/\d+)+(?=\/\d+$)/)[0];
console.log(fixedUrl);
