these questions really helped me, is there any chance to give a chinese version a shot? I would love to contribute : )

When executing the code from the question 19 example, the following error is thrown:

• Type 'number' is not assignable to type 'TeardownLogic'.(2322)

I've created a PR with a fix for this issue,
@sudheerj Please review

All the best

You have done a good work on the angular interview question thing but it has been expired.

If you remove the table styling, you can have auto incremented numbers. However, the code examples would require extra indents to not reset the count. See Stack Overflow.

I mention this because such a change makes it easier to add and remove content.

Please add the below question & answers.
What are the Route Parameters? Explain each of them.
Required, Optional & Query parameter

Grammatical mistakes in question 34.

Please add question & answer about ng-content.

Point 18: How is Dependency Hierarchy formed?

There is no description.

Hi there,

you mention 3 parts of the ngModule, but there are two more and one of them is "essential":
-the providers array, where you have to register your services
-entryComponents, the components which can be dynamically loaded to the view.

could you please update your answer?
Cheers,
Gary

Lazy loading is one of the most useful concepts of Angular Routing.
It helps us to download the
web pages (no, it should be the frontend javascript bundles generated by angular)
in chunks instead of downloading everything in a big bundle.

so many incorrect answers.

how to download interview questions for angular as PDF.
I am not able to download saying output as expired.

1. I don't think the answer was given at all.
2. The statement it is preferred to move all of your Angular bindings to ngOnInit method is wrong, constructor has its own job as well as ngOnInit.

I think this answer is more applicable:

Constructor is the default method for a class that is created when a class is installed and ensures the proper execution of the roles in the class and its subsections. Angular is preferably the Dependency Injector (DI), analyzes the builder’s components and when creating a new feature by calling the new MyClass() tries to find suppliers that match the builder’s parameter types, resolve them and pass them to similar components.

ngOnInit: OnInit is a life cycle widget called Angular to show that Angular is made to create a component.

Differences:
We use constructor() for all the initialization/declaration.
It’s better to avoid writing actual work in the constructor.
The constructor() should only be used to initialize class members but shouldn’t do actual “work”.
So we should use constructor() to set up Dependency Injection, Initialization of class fields, etc.
ngOnInit() is a better place to write “actual work code” that we need to execute as soon as the class is instantiated.
Like loading data from Database — to show the user in your HTML template view. Such code should be written in ngOnInit().
