Top 50 Angular Interview Questions

[@jd-9]

I just faced an interview, the interviewer asked me 15 questions. I gave him 12 correct answers because of your video. +1 Subscribers. I'm not sure if they'll hire me since I was wrong for 3 times. Not just that, I've been away from Angular for like an year and almost forgot all the things, your video refreshed my memory, and brought me back those old memories I've had with Angular. This is the kind of crash course everybody should follow. Seriously, it's like a crash course covering most of the important Angular topics. Thanks, and wish me luck!

[@interviewhappy]

Your welcome JD . Wishing you all luck brother.

@1:40:58 Observables are not always lazy. Cold observables (such as HTTP requests) are lazy, but hot observables (such as WebSocket streams) are eager.

I had forcefully worked on Angular in my previous projects but to mention in my resume I was not sure how to handle interviews. After I completed this video I have better understanding of co-relating concepts to my work. Thanks a lot for your effort to make these kind of videos

Angular has good future because it is too good and the companies are not able to find candidates for this.

The video is very use full and I have a doubt, what is the difference between class and ngClass in angular

[@interviewhappy]

The class attribute apply one or more static CSS classes to an element. That'st it But The ngClass directive in Angular allows you to conditionally apply CSS classes based on certain conditions or expressions.

[@readlearnandexplore4540]

Thank you for all the hard work. 1.Where we mostly use 2 way data-binding in realtime? 2. What are the differences b/w directive and Decorator?

[@_rgv_raghav_]

Hi, I would like to answer your questions with context of this video only, decorators are used to store metadata like for a component its metadata are its HTML, css etc which we are provided in @component({ }). directives are basically which we used to implement some logic within our HTML or by adding/removing style in our HTML *ngIf, [ngStyle]. two way data binding we use mostly in search filters, where user need to input value for filter condition and same input value if we want to post on our grid or some other field.
