Javascript: How to use reduce?

Working with arrays on javascript, the reduce function has been really helpful.

Reduce has 2 arguments:

First argument is the call back function that is called for each element of the array.

Second argument is initial value that you want to specify and can be optional.

You can use it to easily add numbers and combine strings.
