Angular Lifecycle: ngOnInit

Introduction

Angular provides a comprehensive set of lifecycle hooks to enable developers to perform various tasks at different stages of a component's life.

ngOnInit: Initializing Components

ngOnInit is a specific lifecycle hook that is invoked after Angular has initialized all data-bound properties of a directive. This hook is commonly used to:

• Fetch data from an external source (e.g., API call)
• Subscribe to events or services
• Perform complex calculations or transformations

By utilizing ngOnInit, developers can ensure that any necessary initialization tasks are executed after Angular has completed its own initialization process.
