✔️ How Angular Components Work Internally?
✔️ Detailed Explanation of Lifecycle Hooks with Examples
✔️ Real-World Use Cases
✔️ Best Practices

By the end of this blog, you’ll have a strong grasp of how Angular components behave and how to use lifecycle hooks effectively! Let’s dive in!

1️⃣ What Are Angular Lifecycle Hooks? 🤔

Every Angular component has a life cycle — it gets created, updated, and destroyed. During these stages, Angular provides hooks (methods) that allow us to execute custom logic at specific moments.

For example, when a component initializes, you might need to fetch data from an API. When a component is about to be removed, you might need to unsubscribe from observables or clear intervals.

✔️ Lifecycle hooks help you handle these events efficiently.
