Arrays and loops

An array is JavaScript's version of a list:

const scores = [12, 7, 30, 18];

console.log(scores[0]);       // 12
console.log(scores.length);   // 4
scores.push(25);              // add at the end

for (const score of scores) {
  console.log("Score:", score);
}

And if you need to count, there's the classic for loop:

for (let i = 0; i < 5; i++) {
  console.log("Lap", i);
}

It reads: start with i at 0; keep going while i is less than 5; add 1 to i after each lap.

Your mission

Using loops (no Math.max allowed, that would be cheating 😉):

1. total(numbers) returns the sum of the numbers (0 for an empty array).
2. biggest(numbers) returns the largest number.
