In Angular, interpolation and property binding are two different types of data binding that serve different purposes. Interpolation is used to display the value of a component’s property in the template, while property binding is used to set the value of a property in an HTML element.

You can use interpolation to set the value of an attribute, but it’s not a recommended practice. Interpolation works by converting the expression inside the double curly braces into a string and then placing that string into the HTML. This means that the expression is only evaluated once during the initial rendering of the view, and any subsequent changes to the component’s property will not be reflected in the view.

Property binding, on the other hand, allows you to bind a component property to an HTML element property, which means that any changes to the component property will be reflected in the view automatically. Property binding is more flexible than interpolation because it allows you to bind to more than just the attribute values of HTML elements.

So while you can use interpolation to set the value of an attribute, it’s not recommended. It’s better to use property binding for this purpose to ensure that changes to the component’s property are reflected in the view.
