Looking for a solution to display data and map values to another presentation without needing complex ngIf statements or creating multiple components.
Check out this sample: https://stackblitz.com/edit/angular-9l1vff
The 'vals' variable contains the data, while 'getVal' performs the mapping process.
Is there a way to achieve this directly in the template without intricate logic or relying on the HTML-sanitizer?
Seeking the most efficient strategy to handle this situation. Any advice?
For a more efficient solution, you can utilize the pure pipe method which is only triggered when the input reference changes, and it can be stored externally to your component implementation.
In the provided example, the function getVal is currently being invoked in each change detection cycle.
To securely sanitize trusted HTML content, consider creating an additional pipe and linking them together.
