Thank You for your response.
I agree Mikhail Tatsky. We will cover all the things one by one. But, there is a quote by bruce lee :
“I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.”
So instead of going through all the technologies without understanding them correctly will not be good for careers also.
Have a nice day Mikhail Tatsky
