How do you convert character to ASCII code

You can use the String.prototype.charCodeAt() method to convert string characters to ASCII numbers. For example, let's find ASCII code for the first letter of 'ABC' string,

"ABC".charCodeAt(0); // returns 65

Whereas String.fromCharCode() method converts numbers to equal ASCII characters.

String.fromCharCode(65, 66, 67); // returns 'ABC'
