Word jumble expression for After Effects

jumble.js

posterizeTime(thisComp.layer("controller").effect("posterizer")("Slider")/2);

// The Array of words to jumble
let words = ['My', 'name', 'is', 'Blonky'];

// the digits parameter below is an Array. It contains the result of all rolling, and determines which word above to choose
function roll(digits) {
  // attempt to roll a number between the first and last word
  let dice = randomInteger(0, words.length - 1);
  // if the number was already rolled, roll again
  if (digits.includes(dice)) return roll(digits);
  else {
    // but if a new number, add to Array and return the value
    digits.push(dice);
    return digits;
  }
}

// Pure random number generator. This is just an example of how AE's random() function actually works in vanilla Javascript
function randomInteger(min, max) {
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

// Create an empty array for the result
let dialogue = [];

// Do something per word Array item
words.forEach((word) => {
  // We pass in the initially empty Array, but it will populate itself with our roll function since that uses .push()
  roll(dialogue);
})
// Now we need to change our roll Array from containing only digits to the actual word equivalents, like word[1], word[3], etc.
// We can easily modify it using Array.prototype.map, which alters every entry of an Array and returns the result
let speak = dialogue.map(item => {
  // expression ? if true do this : else false do this -- this is one-line shorthand for if/else:
  return randomInteger(0,1) ? words[item].toUpperCase() : words[item].toLowerCase();
  // The new Array entry returns words[randomNumber], jumbling our initial array.
  // If rolls a second time between 0 and 1, if 0 it returns all uppercase, else returns lowercase
})

// Finally join the newest array with a delimiter, a space character. This automatically converts it from an Array to a String
speak.join(' ');
