Q39. Wha is the use of ngAfterViewInit?
Answer 39:
Angular ngAfterViewInit() is the method of AfterViewInit interface. ngAfterViewInit() is a lifecycle hook that is called after Angular has fully initialized a component's views. ngAfterViewInit() is used to handle any additional initialization tasks.
ngOnInit() is called after ngOnChanges() was called the first time. ngOnChanges() is called every time inputs are updated by change detection.
ngAfterViewInit() is called after the view is initially rendered. This is why @ViewChild() depends on it.

Q40. What is Transpiling and compilation?
Answer 40:
Transpiling is a process of converting your typescript code into Javascript code using transpilar.
Transpiling code is a similar concept to the compilation process, with one big difference. Compiling: code from a high level language is get converted to machine level language. Transpiling: code from a high level language gets converted to another high level language
