How can I optimize pipes in Angular CLI?

How can I optimize pipes in Angular CLI?

To optimize pipes in Angular, you can use pure pipes, which only re-evaluate when their input changes. This reduces unnecessary calculations.

What are pure and impure pipes?

Pure pipes only execute when their input reference changes, while impure pipes run on every change detection cycle, which can be less efficient.

Can I use memoization with pipes?

Yes, you can implement memoization in your custom pipes to cache results and avoid recalculating outputs for the same inputs.

Are there any built-in pipes that are optimized?

Yes, Angular provides several built-in pure pipes like DatePipe, CurrencyPipe, and DecimalPipe that are optimized for performance.

How do I create a custom pipe?

You can create a custom pipe by using the @Pipe decorator and implementing the transform method to define the transformation logic.
