Why is the return value for .forEach() always undefined?

const fruits = ['mango', 'papaya', 'pineapple', 'apple'];

// Iterate over fruits below
fruits.forEach( fruit => {
  let indefiniteArticle = '';
  if (fruit[0] === 'a' || fruit[0] === 'e' || fruit[0] === 'i' || fruit[0] === 'o' || fruit[0] === 'u') {
    indefiniteArticle = 'an';
  //else if (fruit[0] === 'h'&& fruit[1] ===) { }
  else {
    indefiniteArticle = 'a';
  console.log(`I want to eat ${indefiniteArticle} ${fruit}`);

/* Added indefinate article conditions. 
For future senerio, implment conditions with words starting with an H.
Also obeying DRY, create an array of vowels to loop through to avoid rewriting each vowels condition on the H comparison. */

I included Indefinate Article conditions to make an apple grammatically correct.


why would this method need to return anything? What matters are the values you get from the array
