byte_operations.js

// Here's how to do basic integer<->byte (string/char) operations in JavaScript. 
// Took me a good while to dig this up.

function intToChar(integer) {
  return String.fromCharCode(integer)
}

function charToInt(char) {
  return char.charCodeAt(0)
}

// Example:

intToChar(90) // --> "Z"

charToInt("Z") // --> 90
