This PR is the solution to the 'js basics' #4

[A-Rohit-Reddy]

• This task helped me dive further into the uses of javascript and its complexities. I also learnt using a backend server to load data and manage data in tables, like adding amount, displaying the detais , etc.
• I faced a lot of difficulty in working with the backend , although I later figured things with help of sources, and was able to understand how the whole process worked.
• I learnt a lot, as to how difficulty small mistakes in the code can lead to, and how much time one has to put in to ensure there are no bugs. Also, I enjoyed backend integration and all, although I couldnt really learn a lot on that matter, but whatever I learnt itself was challenging.
