How to remove last segment from URL with JavaScript?

To remove last segment from URL with JavaScript, we can use the string’s slice method.

For instance, we write:

const url = 'http://example.com/foo/bar'
const newUrl = url.slice(0, url.lastIndexOf('/'));
console.log(newUrl)

We call url.slice with the indexes of the start and end of the substring we want to return.

The character at the end index itself is excluded.

We have url.lastIndexOf('/') to return the index of the last / in the URL string.

Therefore, newUrl is 'http://example.com/foo'.
