- [Instructor] The first time I realized I wanted to write angular code was when I saw someone demonstrate two-way binding. Angular enables two-way binding and form controls using NG model, but it also enables two-way binding between components. Two-way binding between components allows child components to propagate changes back to their parent component. Creating inputs that could instantly affect elements and other components was not an easy feat in vanilla JavaScript. Angular made it a lot easier, but setting up two-way binding with decorator based inputs and outputs required very specific boilerplate code.
