Alan did some team training today. We had Brandon, Alan, Bryan, Dustin, Josh, Russell, and Wayne on the meeting. The main topics today were dealing with closures such as map, reduce, filter, and each.

- Using each - iterate through each element.

- Using filter - limit records based on a specific condition.

- Using map - modify or transform each element.

- Using reduce - convert data into new type.

- As a syntax help tip... most of the closures have this format for the possible arguments - value, index, array or key, value, struct.

- Alan like the reduce function - lots of power. As a note, when using reduce, there is a previous and a starting value (where did you start and what are you currently working with that was possibly altered from a previous loop).
