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

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
5 ай бұрын
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.
Synchronous is a blocking architecture,
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.

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.

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 ?
