Arrays in JavaScript - Difference between forEach(...

27.

What is the difference between the forEach() method and the map() method when looping through array elements?

The forEach() method modifies the original array, while the map() method returns a new array.

The forEach() method performs a callback function on each element, while the map() method transforms each element and returns a new array.

The forEach() method only works on arrays, while the map() method can also be used on objects.

The forEach() method is used for looping through multidimensional arrays, while the map() method is used for looping through single-dimensional arrays.
