Question

I have the strings below and I am trying to remove the last directory from them but I cant seem to get the grasp of it.

JavaScript

var x = path.split("/")
alert(path +' = ' +x.slice(0, -1));

Expected Result

/foo/bar/ = /foo/
/bar/foo/ = /bar/
/bar/foo/moo/ = /bar/foo/

Answer 1

Try:

let path = "/bar/foo/moo/";
let split = path.split("/");
let splicedStr = split.slice(0, split.length - 2).join("/") + "/";
console.log(splicedStr);
