For Each

The forEach method executes a provided function once for each array element. Here's the syntax for using forEach:

array.forEach(function(element, index, array) {
  // element: current element being processed in the array
  // index: index of the current element being processed in the array
  // array: the array forEach was called upon
});

For example, let's say you have an array of numbers and you want to print the double of each number to the console. You could do this using forEach like this:

let numbers = [1, 2, 3, 4, 5];
numbers.forEach(function(number) {
  console.log(number * 2);
});

You can also use the arrow function syntax to define the function passed to forEach:

numbers.forEach((number) => {
  console.log(number * 2);
});

or

numbers.forEach(number => console.log(number * 2));

The forEach method does not modify the original array. It simply iterates over the elements of the array and executes the provided function for each element.
