230,688 PointsThe "map" method will run a function on each element, collecting the returned values into a new array, and when it finishes it returns that new array.
On the other hand, a "forEach" will run a function on each element, but it ignores any returned value from the function and it doesn't return anything itself.
So you would use "map" instead of "forEach" when you want to get an array of returned values back.
