Evaluate Code Questions for Array.forEach Test

const ratings = [5, 4, 5];
let sum = 0;

const sumFunction = async (a, b) => a + b;

ratings.forEach(async (rating) => {
  sum = await sumFunction(sum, rating);
});

console.log(sum);

[2, 5, , 9].forEach(function(element, index) {
    console.log(`a[${index}] = ${element}`);
