How to I format an integer with leading 0's in javascript

Question

I need to format a string so that it looks like:

"Expect 000062" in javascript.

In C# I do this:

String expect = String.Format("Expect {0:000000}", data.Length);

In Swift I do this:

var expect = NSString(format: "Expect %06d", data.length)

How do I do this same thing in javascript?

Try something like this:

var Num = "64";
var nNum = ("000000" + Num).slice(-6);
console.log(nNum);
