Hey!

Sorry, but we will have to disagree. I actually recommend you to break the server legs entirely, so it can't walk anymore. 😅

See how many errors you can get and try to beat your previous highscore!

Then fix the errors one by one, patiently. You will get some big headaches, for sure, but in the end you will know Node.js by heart. Thank me later! 😅

You’re hilarious, Alex! 🙃🤣 That one really got me! 😂 So this is your new way of learning, huh...? 😉🙃
From what you said, I’m guessing you crashed the server learning Node.js before I even got there... 😂🤗
I’ll share my score too, let’s see who had more bugs! 😂🤗
See you around, and good luck with your studies! Thanks for your time!

Great article! I spent all summer learning frontend development, and recently started building my first full stack app. I ran into all of these issues when working with node.js, particularly the "commonjs" vs. "module" thing

Thank you for your time!🤗 I’m glad my post was helpful for you.
I wanted to focus on the fundamentals we need to pay attention to in Node.js, once you understand their purpose, you won’t really have to worry about them anymore.
So it’s completely normal to run into them at first.😊
Happy coding, and good luck with your learning and your project!

How long were you into frontend before deciding on moving to backend now?

I've been on this path for 1 year and just** a few days ago** I started doing backend. 🙃It depends on your learning type, the journey could take a while until backend or could be faster, it depends how fast you learn.

Me personally I'm that person who spends some deep time while learning new things, exercising with what I've been learning... It is important to understand the concepts, don't just go forward.
Avoid tutorial hell as much as possible. No matter where you are with your journey, enjoy your path!
Good luck with your learning and if you are afraid about backend...just don't be, it is not so bad. 🤗
