What is an Angular pipe and how do I create one?

An Angular pipe is a way to transform data in your templates. You can create a custom pipe by implementing the PipeTransform interface.

Can you show me a simple example of a custom pipe?

Sure! Here's a simple example: create a file named 'exponential-strength.pipe.ts' and implement the transform method to return the exponent of a number.

How do I use this pipe in my component?

You can use your custom pipe in the template like this: {{ value | exponentialStrength: exponent }}.

Are there built-in pipes I can use?

Yes, Angular provides several built-in pipes like DatePipe, CurrencyPipe, and DecimalPipe that you can use directly.
