JavaScript has a few different array methods, each of which is useful for different cases. The Array.reduce() method is one such method. While the reduce() method might seem confusing at first, it’s definitely one that all developers should have in their toolbox. The reduce() method takes an array, performs a set of actions on each element of the array, and reduces it to one single value.

The reduce function takes the following syntax:

array.reduce(reducer, initialValue)

// the initialValue argument is optional

As shown above, the reduce() method takes two arguments: a reducer function and an optionalinitial value. Let’s now dive deeper to see what is actually happening under the hood of this reduce() method.
