For example, you might use it for multiplying all the elements of the array by a certain number as we have seen this in the above example.ģ.) Asynchronous operations: forEach() method can also be used with asynchronous operations, such as making HTTP requests or reading from a file. We have seen this in the above example.Ģ.)
