Iterating through Arrays with forEach

One method to iterate through an array in JavaScript is forEach(). This method goes through each element of the array one at a time and can be useful when applying operations to specific elements within the array.

Call a function on each element in an array

This example uses the forEach() method to call a function on each element in the fruits array; the function causes each item to be logged to the console, along with the item's index number.

const fruits = ["Apple", "Mango", "Cherry"];
fruits.forEach((item, index, array) => {
  console.log(item, index);
});
// Apple 0
// Mango 1
// Cherry 2
