What are some common mistakes to avoid in Angular?

Some common mistakes in Angular include not using the OnPush change detection strategy, neglecting to unsubscribe from observables, and not using Angular's built-in features like pipes and directives effectively.

Can you explain why unsubscribing from observables is important?

Unsubscribing from observables is crucial to prevent memory leaks in your application. If you don't unsubscribe, the observable may continue to emit values even after the component is destroyed, leading to unnecessary resource consumption.

What is the OnPush change detection strategy?

The OnPush change detection strategy optimizes performance by checking for changes only when the input properties of a component change or when an event occurs within the component. This reduces the number of checks Angular has to perform.

How can I effectively use pipes in Angular?

You can use pipes in Angular to transform data in templates. For example, you can use the built-in DatePipe to format dates or create custom pipes to encapsulate complex transformations, making your templates cleaner and more readable.
