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..

🙏🏻✋🏻

[harshpatil]

Que #7. Answer is wrong
Synchronous, Blocking functions
Asynchronous, Non-blocking functions

[MuhammadAwais-]

it was quite informative, but it would be better if you would provide examples as well along with each answer, thanks :)

[harisali]

8:00 => synchronous Api - blocking, Async - non blocking

[AkshatJainBafna_]

Performance, flexibility, scalability, real time abilities, efficiency, ease-of-use, time & space complexity, robust, reliable, minimalism, fast, and you are good to go.

[ooomr.kibeautifulmiss]

It is not a language ... it's just javaScript runtime environment... JavaScript is a language...

[usamalucky]

Great Information .Please Make Complete Tutorials On NodE Js

[manu]

Single Threaded, means synchronous processing, it uses event loop to achieve asynchronous architecture.

[vikramjeetsinghh]

It would be better if you provide code example also so that we can know how and where to use these things

[prishasaini_official]

In this video, you are explaining Synchronous API = non-blocking code and Asynchronous api = blocking code, Is is correct information??

[chat-]

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

[priyankaable]

Questions are good but I am not happy with the explanations . sorry to say .but you have used many technical words which become over flow . please use simple words so that we can understand clearly . We prefer videos instead of blog to avoid such typical word's.

[gayathrichennakrishnamshar]

if node.js is good for small to mid-sized applications, how is that accounting for scalablility?

[CodePressAcademy]

Synchronous is a blocking architecture,

[dawoodshahzad]

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

[kiransavlani]

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 ?

[ram.]

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.

[akashbhat]

Can you please share the pdf which was used for explanation ?
