Title. I’m currently doing the #100DaysOfCode challenge, so I’m wondering if this could work. I’ve never really coded before, and I’d like to finish at least -something- before 2027. Any input is appreciated.
I can’t answer, it depends how much time you spend to solve each lab and workshop step. I would not call it realistic tbh
Welcome to the forum @vinicius
Each certificate states that it represents approximately 300 hours of work.
What’s important is the quality of the learning, not the quantity. Learn the fundamentals, spend time reviewing and practicing what you learnt. If you don’t allow yourself enough time to absorb the material you may find you didn’t actually learn much.
Repeat any sections you find challenging. At some point you will be asked to combine several different aspects.
Happy coding
I think it is possible. I did it after learning few months and make a website live for a friend who has a medical condition. How much burning you are for your desire to finish ?
I’d say go for it! If you’re starting from zero, don’t worry too much about building something impressive right away. The main goal of #100DaysOfCode is to build the habit and learn consistently.
Even if you finish the 100 days knowing how to make a small website, a simple game, or a basic app, that’s still a huge accomplishment compared to where you started. Just focus on showing up every day and making a little progress.
You’ve still got plenty of time before 2027—good luck! 
I guess it really depends on your learning skills. If you never ever coded before, I suggest you start by the responsible web design because a part of the JS curriculum is based on some html and css knowledge (it’s still possible to start with JS, but I think it’s way harder). Maybe Python could be more beginner-friendly than JS, but honestly that’s totally your choice, and if you’re aiming for learning front-end then the html/css/JS is the best that you can learn here.
If you’re ready to invest more than an hour a day, ig it will take less time to finish them, but really go at your pace and don’t be afraid to spend more time on a specific notion, or going back because you didn’t really understand. Remember: it’s not a sprint, it’s a marathon.
That being said, you’ll have plenty of little projects, apps and stuff you will build along the way by the end of any of these courses (and by the end of 2026) so go for it! Have fun in your coding journey!
