What is Property binding in angular?

Property binding Passing data from Component to View Template. But we cannot use any type of string concatenation with property binding. In the below example

Property binding directly applied on property of DOM. Whereas string interpolation internally converted to property binding before applied to the DOM. Interpolation is a special syntax that Angular converts into a property binding. Interpolation is just a convenient alternative to property binding. We cannot use all the places interpolation and property binding. For example, we have a button on the html page and we want to make it enable and disable as per the condition. At that time property binding will work where as if we use interpolation the button becomes disabled or enabled all the time even if its value changes.
