Angular has more powerful event-handling capabilities compared to Angular 1.x. Angular 1.x has two-way data binding, whereas Angular doesn't recommend that. Angular handles the communication between data and templates through the power of events.
Angular projects stand on the combination of some components. To function, these components need to communicate with each other to share data and events. Mostly, components need to communicate when they have a parent-child relationship. There are a few ways in which Angular can communicate between parent and child components. The best is by handling custom events. We will look at details about custom events and see how they work with our search application.
