Component Lifecycle Hooks
Explore the various lifecycle phases of Angular components and how to use lifecycle hooks such as ngOnInit, ngOnChanges, and ngOnDestroy. Understand when these hooks execute and how they help manage component creation, updates, and destruction effectively within your application.

A component grows and goes through multiple phases throughout its life. Using and controlling these phases using lifecycle hooks helps you get a better hold of your application.

Constructor
A constructor is invoked when Angular creates a component using the new keyword in the class.
ngOnInit
This is invoked when the component initializes and gets the data.
