I was doing job as a software engineer since 2 years but still I have a huge fear of coding and I always try to avoid writing the code. Last month I got laid off from my company as a part of mass layoff. Market is not good these days and I am struggling so much to get a new job. During this phase, I realized I need to learn coding and get rid of my fear if I want to get a new job quickly. In this hard time, I am learning coding from this playlist and gaining some confidence that it's not that tough what I always used to think. Thank you so much Harry bhai for this valuable content. I am writing this comment on 26/7/2024, 11:32PM & will come back and edit this when I'll get a job. Need everyone's blessings who is reading this so that I can come back as soon as possible. Wish me luck guys!!
