Angular 2 (Angular 4) – Lifecycle Hooks – OnInit, DoCheck and OnDestroy hook.

In this video I introduce three more hooks in the Angular 2 lifecycle. These are the OnInit, DoCheck and OnDestroy hooks. I go through the understanding of each one, and how they are called based on whether they are in a parent component or a child component.

We look at the ordering of how parent and child components are initialised and destroyed, and how each component ngDoCheck function is called regardless of what input is changed in our angular 2 application.

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