forEach() is a high-order array method that executes the provided callback once for each element in the array.

First we reference the array then add .forEach(). Within forEach() we put our function or callback. The callback can have up to 3 arguments; the current element value, the current element index, and the entire array being iterated. To iterate basically means to loop through each item.

High-order array methods make tasks more simple, expressive, readable, reusable, maintainable, and elegant.

I'll be releasing a new video every day in January! Stay tuned..
