    The 1st answer is wrong so I didn't watch further.. 1st of all Node Js is not a programming language it's a Javascript runtime environment. Pls make sure you're making right content cause 1000s of people are relying on this video. And it's quite bad that you come up with false info..

    • @elelemakelele7440
      @elelemakelele7440 4 роки тому +3

      No, it's not correct info. Non-blocking is async and blocking operations are synchronous. nodejs.org/en/docs/guides/blocking-vs-non-blocking/

    8:02 guys, he's making wrong statements like synchronous means blocking, Asyn means non-blocking which is generally used in node.js but in video vise-versa ...intellipaat literally felt like shit u guys are doing a lot of efforts to make videos but with wrong information.

    • @abhishekdalakoti2663
      @abhishekdalakoti2663 4 роки тому +1

      What they said is correct you didn't understood the English . They wanted to say that async api are used where there is blocking code and sync where there is non blocking code.

  • @divyasri7646

    Great Tutorial as I am beginner in Node Js so have one doubt
    in Video below thing is mentioned :-
    "There are two types of API functions. They are as follows:
    Synchronous APIs: Used for non-blocking functions
    Asynchronous APIs: Used for blocking functions"
    Is not Synchronous for blocking and Asynchronous for non blocking ?

    On #5 you said angular can do everything node can do this really confusing me ... can angular do serverside things like connecting db without exposing db credentials

    • @Intellipaat
      @Intellipaat  3 роки тому

      Hi Yusuf, Kindly be informed that Angular runs into the browser, and its context is limited to that. If you need to connect to a database, you need to use some backend technologies, like express and node js.

    are you sure that Synchronous APIS is used for non blocking functions and Asynchronous APIS are used for blocking?

    • @Intellipaat
      @Intellipaat  11 місяців тому

      You've actually got that reversed! Synchronous APIs are the ones that block, meaning your program waits for the function to finish before moving on. Asynchronous APIs, on the other hand, let your program keep running while the function works in the background.
