What does the `forEach()` method do?

The forEach() method is a built-in JavaScript array method that executes a provided function once for each element in the array. It is primarily used for iterating through the elements without creating a new array or returning any value. When called, it takes a callback function as an argument, applies this function to each element of the array sequentially, and passes the current element, its index, and the entire array to this callback.

This method is particularly useful for performing operations like logging values, modifying external variables, or executing side effects, but it does not return a new array or filter the elements based on conditions. Consequently, when utilizing forEach(), you can focus on the actions to be performed on each element rather than expecting a new array as output.

In contrast, other options describe functionalities that are not part of what forEach() is designed to do, such as returning a modified array, filtering items based on certain criteria, or accumulating values. These operations are carried out by other methods like map(), filter(), and reduce(), respectively.
