Requirements for front-end positions, "experience using Angular.js is preferred".

Question

I just learned AngularJS and there was an incident where I also used the MEAN technology stack to build an essay station (similar to a personal blog).

I saw some front-end requirements saying "experience with Angular.js is preferred". What are the specific requirements? Or as an interviewer, what questions would you ask candidates about AngularJS?

Answer 1

1. What mechanism does angular use for data binding? Describe the principle in detail

7. What are the disadvantages of angular?

8. What do you think of the controller as syntax introduced in angular 1.2?

9. Details angular's "dependency injection"

Answer 2

If it were me, these two aspects would be:

1. First check the authenticity of the information you say:
   For example, you will ask some common questions, how long it took to develop the project, what problems were encountered in the process, how were they solved, etc.
   Understanding this is mainly to check whether other information on your resume is true.

2. What you understand about angularjs, or the so-called personal development worldview:
   Understanding this is mainly to screen whether the information you have is consistent with the company's job requirements.
   For example, the similarities and differences between angularjs and react, the future of angularjs, etc.

For reference only.

Answer 3

Generally, interviewers like to ask you about the implementation mechanism or principle of Angular two-way binding. You can prepare for this.
If it were me, I would also ask about several communication methods between Controllers, between father and son, between brothers, etc.
