The code you’ve shared is written in TypeScript and Angular’s template syntax. Here’s a breakdown of how it works: TypeScript Method (openDialog) : This is a method defined in your TypeScript component. It takes an event object ( $event ) as a parameter. The $event object represents the DOM event that triggered the function call. In this case it would be the click event. openDialog($event:Event){ this.openModal.emit($event); } When this method is called it emits an event ( openModal ) with the $event object as its payload. The emit method is used to send custom events from child components to their parent components in Angular. HTML Markup : This is the HTML template associated with the same TypeScript component. It includes a button with a click event listener. add The (click)=openDialog($event) part is an Angular event binding. It listens for the button’s click events. When a click event occurs it calls the openDialog method and passes the click event object ( $event ) to it. So when you click the button it triggers the openDialog method in your TypeScript component which in turn emits the openModal event with the click event object. This can be useful if you have a parent component listening for the openModal event as it can react whenever the button is clicked. Hope this helps! ??
