Transform Data with Angular @Input()
Starting with Angular v16.1, we can now transform data using the @Input() decorator.
The @Input() decorator identifies an input property. We can use an input property to receive a value from a parent component. Or read a route from the URL.
The @Input() decorator provides three additional feature options for our input properties: alias, required (v16), and transform (v16.1). This video briefly describes the first two, then focuses on data transformation.
