25 Input Custom Property Binding Angular Components Directives

In this lecture you will learn how to bind a custom property of a component class using @input decorator & how to pass data from parent component to child component using custom property binding.

In this lecture you will learn how to bind a custom property of a component class using @input decorator & how to pass data from parent component to child component using custom property binding.
