codejam 2020 review

I am a first-year engineering student and I participated in Codejam 2020 This was my first codejam and my first coding competition too I used Node.Js for the competition as I am pretty fluent in JavaScript Though JavaScript is a very popular programming language, within a few problems I realised that it's not very perfect for competitive programming the qualification round was extremely easy and anyone with decent programming knowledge would qualify easily since, this was my first attempt in competitive programming, I was not very prepared for algorithm stuff this, along with many other factors was the main reason of my failure
