Map() Method in JavaScript: A Step-by-Step Guide for Beginners

Hello brother I hope you will reply to my message. Please🙏
I am 2024 graduate in Mechanical Engineering from tier 2 college. I was placed in a sales job in Jan at 45k/month
In March I was placed in trading job at 25k/month
I rejected the offers for better posts.
But Since April on average 7-8 companies / months have been coming.
Long story in short
Like every others I got some inclination in web dev
Javascript- ReactJS one.
I have made a Amazon clone in pure JS
I may get sales job through college but still I have made some confession with me
1)

But I have many questions and I want you to clear all of them
1. I have made a 70 days target to make react project
2. Can you tell how many
A) only react
B) only JS
C) with Next JS
Projects should I make??
3. What kind of project should I make??
4. How much salary should I expect as fresher (as can get 40k sales job through on campus)
5. Are my timeline achievable (70 days)??


PLZZZZZ REPLY TO EACH POINT
