Here is the example:

var charCode = "a".charCodeAt(0);
console.log(charCode);

Or if you have longer strings:

var string = "Some string";

for (var i = 0; i < string.length; i++) {
  console.log(string.charCodeAt(i));
}

String.charCodeAt(x) method will return ASCII character code at a given position.

@Andrew ASCII is a subset of Unicode, so it's actually the same in this case. (Actually, Unicode is not an encoding, and ASCII is, so in that sense they are different. But for the purposes of `charCodeAt`, there's no difference). – Nateowami Apr 30 '17 at 14:56

This won't work. it will take only 's' – Oguz Dec 01 '19 at 10:37
