UTF-16StringValue.js

// Write a function that determines and returns the UTF-16 string value of a
// string passed in as an argument. The UTF-16 string value is the sum of the
// UTF-16 values of every character in the string. (You may use
// String.prototype.charCodeAt() to determine the UTF-16 value of a character.)

const utf16Value = (string1) => {
  let sum = 0;
  for (const element of string1) {
    sum += element.charCodeAt(element);
  }
  return sum;
};

console.log(utf16Value('Four score'));         // 984
console.log(utf16Value('Launch School'));      // 1251
console.log(utf16Value('a'));                  // 97
console.log(utf16Value(''));                   // 0

const OMEGA = "\u03A9";             // UTF-16 character 'Ω' (omega)
console.log(utf16Value(OMEGA));
