Angular 2 (Angular 4) – Lifecycle Hooks – OnChanges hook

Firstly I want to say MERRY CHRISTMAS!!! Consider this video as a present as I’m publishing this on Christmas day (even though I recorded it on Christmas Eve).

This video introduces the first event that is part of the lifecycle hooks for Angular Components. That is the OnChanges event. I go through the understanding of how it work with Input values.

Also in this lesson I look at Output variables, which emit events to the parent component and how those work as well.

There is no github repository for this video. Just simply follow along. It isn’t that difficult.
