When everything is coded by AI, our greatest quality is to be human. I love @@travisdotmedia videos because he’s particularly honest about the fact that there’s work to do if one wants to become a decent engineer.

More HTML and CSS projects today! I can't wait to dive into JavaScript, but I have to admit, I’m being slow. Slow and steady wins the race, right? 🐢💻

Days 10-11/ #100daysofcode have been slower but incredibly helpful. I’ve always seen myself as a backend engineer, but I’m realizing how valuable it is to have design knowledge and opinions, especially in start-ups. That’s exactly what I’m diving into this week with @freecodecamp

I have to praise this account and their creativity to document coding journey. I just love it! 🥰
day 42 of #100daysOfCode

Oh my gosh, I am happy with how my project turned out- but I am so ready to go on to the next project. I got through some more failures, but found a beginner mistake: putting an unnecessary rule in the top of the CSS instead of where it needed to go. That is how we learn.

Day 8-9/ #100daysofcode. I worked on some CSS lectures. I learned a few things about crawlers and search engine optimization, but I definitely need to be more diligent in the next few days since I already lost my streak 😔
