Give me this pdf of ans?
Ответить
if node.js is good for small to mid-sized applications, how is that accounting for scalablility?
Ответить
Single Threaded, means synchronous processing, it uses event loop to achieve asynchronous architecture.
Ответить
Question 7 answers are swapped it
Ответить
Performance, flexibility, scalability, real time abilities, efficiency, ease-of-use, time & space complexity, robust, reliable, minimalism, fast, and you are good to go.
Ответить
Too much fast, difficult to understand properly , also you need to give some examples on it so beginners can clearly learn from basics. information is great but the way of teaching has to be improved. and also you provide wrong information on blocking and non-blocking. please correct this
Thank you
Synchronous is a blocking architecture,
Ответить
QWESTION NUMBER 7 => ANSWER IS WRONG
Ответить
@intellipaat please correct this
Synchronous is a blocking architecture, so the execution of each operation is dependent on the completion of the one before it
Asynchronous is a non-blocking architecture, so the execution of one task isn’t dependent on another.
you have made easy concept so much jargons...🥲
Ответить
It would be better if you provide code example also so that we can know how and where to use these things
Ответить
Thanks bro
Ответить
Can you please share the pdf which was used for explanation ?
Ответить
It is not a language ... it's just javaScript runtime environment... JavaScript is a language...
Ответить
Q7 is the wrong answer.
Ответить
Asynchronous - non blocking API
Ответить
Thanks for the video..
Ответить
#20: how about nest framework?!
Ответить
Que #7. Answer is wrong
Synchronous, Blocking functions
Asynchronous, Non-blocking functions
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.
Ответить
it was quite informative, but it would be better if you would provide examples as well along with each answer, thanks :)
Ответить
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
Ответить
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..
🙏🏻✋🏻
In this video, you are explaining Synchronous API = non-blocking code and Asynchronous api = blocking code, Is is correct information??
Ответить
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 ?
Great Information .Please Make Complete Tutorials On NodE Js
