    Hi Sir, I am a regular viewer of your videos. I would like to buy your Angular interview questions course on Udemy. When I checked Udemy, I saw two courses: one is "Angular Interview Master Class: Top 100 Questions" and the other is "Angular & JavaScript Interview: Top 400 Questions." Are the Angular questions in both courses the same? Also, if you make any updates, such as adding new questions related to Angular, will they be available in both courses?
    My concern is that I am more focused on Angular, so if the Angular content in both the JavaScript and Angular course and the Angular-only course is exactly the same, I would prefer to buy the JavaScript and Angular course. Please help me.

    • @interviewhappy
      @interviewhappy  4 หลายเดือนก่อน +1

      Yes, Angular content is same in both courses. In Top 400 questions, JavaScript content is extra.
