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,
1 | "ABC".charCodeAt(0) // returns 65 |
Whereas String.fromCharCode() method converts numbers to equal ASCII characters.
1 | String.fromCharCode(65,66,67); // returns 'ABC' |
