a) During object creation
b) For dependency injection
c) To perform work independent of DI, DOM, or input bindings
d) After ngOnChanges but before the constructor

Answer 1

The ngOnInit method in Angular components is commonly used to perform work independent of dependency injection (DI), DOM manipulation, or input bindings.

Step-by-step explanation:

The ngOnInit method in Angular components is commonly used to perform work independent of dependency injection (DI), DOM manipulation, or input bindings.

This method is called after the component has received its input properties through ngOnChanges and before the constructor is executed.

An example of using ngOnInit is when you need to fetch data from an API or perform any other initialization tasks when the component is being created.
