  • Do you need classes in JS/TS? 2025 version
    1 project | dev.to | 18 Mar 2025
    So is it good or bad to use classes? In my opinion, classes are great solutions to a set of particular problems. Using them outside of these problems is adding noise to your codebase. If you don't know how else to write structured code, then it means you must invest in learning more about JavaScript and TypeScript. For further reading I really recommend the books by getify - You don't know JS; class alternatives.

  • Why I Strongly Believe Knowledge Should Be Free
    1 project | dev.to | 16 Dec 2024
    I was strongly against my parents sending me to private university. I wanted to enrol in a vocational school, to save money most. I had zero faith in our countries education system. And I was not wrong. The university curriculum was vastly lacking in what I knew was standard in the industry. Had I not been working in the industry at the time, my career prospects would have been much worse.. By the time I got a job in Cefalo, one of Bangladesh’s best software companie­s, my parents could no longer force me to stay in school. I dropped out two years into uni. It had nothing to do with me getting this job. I owe most of my success to Kyle Simpson and Eric Elliott. Kyle's YDKJS taught me the funda­mentals of JavaScript. I had not bought his books, rather borrowed them. I am already trying to fix that mistake by gifting some of my students the books. On the other hand, all the blog posts that I read from Eric Elliott were the fundamentals of my coding standard. One of my colleagues in Cefalo pointed out that I got the job because I wrote unit tests-- something engrained in me by Eric. Unfortunately, I could never afford his paid mentorship. Where would my career have been if I had had that opportunity? I wonder.
