Difference between Compile Time Errors and Run Time Errors Compile-time During compile time the source code is converted into an executable code. Run time During the run time the executable code which is generated during the compile time, is started running. Both the compile-time and runtime refer to different types of error.

Semantic errors The semantic errors occurs when the coding statements are not meaningful to the compiler. After correcting the semantic error, Run time errors O

Event binding syntax will have a target event name within parentheses on the left of an equal sign, and a quoted template statement on the right. Eg 1: In this example I used a button to demonstrate the event binding. In here we are binding an onClick() event to the button element. When the user clicks on the button, event binding listens to the button's click event and calls the component's onClick() method in component.ts file. Eg:2 . In here there is a method named "onUpdateServerName" and add an event with it.
