My first React app was a mess, then I redid it 6 months later

I built a simple todo app when I first started learning React last January. It worked but the code was this huge tangled thing with state all over the place. I came back to it in July after learning about hooks and context, and rewrote the whole thing in about 200 lines instead of 600. Has anyone else gone back to an old project and been surprised at how much cleaner you can make it?

I'm split on whether beginners should start with Python or JavaScript first

I met this guy at a coding meetup in Austin last month who swore that if he hadn't started with JavaScript, he'd have given up after week one. He said Python's syntax was too abstract for him and he needed to see buttons and browser output right away to stay motivated. But another friend tells me Python teaches you logic better and keeps you from picking up bad habits from JS's loose rules. Has anyone else dealt with this fork in the road and regretted going one way?

Wrote my first Python script that actually did what I wanted after 8 tries

I tried to automate renaming a bunch of photo files and after 8 failed attempts it finally worked, which taught me that reading the error messages carefully is more important than just guessing what went wrong; has anyone else had a moment where a simple script took way longer than you expected?

Took me 3 weeks of debugging to realize I was using single equals instead of double equals in JavaScript

I spent hours staring at a loop that kept giving wrong values, and it turned out I was assigning instead of comparing, why does nobody warn beginners about this one dumb mistake?

Rant: Lost a whole afternoon because I didn't commit my code before a merge

I was working on a simple website project last Tuesday, sitting in my home office around 3 PM. I had about 4 hours of changes to a CSS file and some new JavaScript functions. Before I knew it, git decided to auto-merge something and it overwrote all my work from that day. Turns out, I was on the wrong branch the whole time and never committed first. Has anyone else had git eat hours of work like this?

How I learned I had been using git branches the wrong way for 2 years

I was at a meetup in Austin last summer and this guy looked over my shoulder while I was merging something. He asked why I was always merging master into my feature branch instead of rebasing, and I had no good answer. I literally thought merging was the only way to keep branches updated (you know, like a dummy). After he showed me rebase -i I felt like I had wasted so much time on messy commit histories. Has anyone else had that moment where a simple tip from a stranger just flipped your whole approach?

Got told my indentation was wrong by a senior dev at my first job

I was 3 weeks into my first coding job in Atlanta and this senior guy walks by my desk, looks at my screen, and says my indentation is all over the place. He said I was using spaces inconsistently like 2 spaces here 4 spaces there. I thought it was just a style thing but he showed me how it actually breaks code review tools and makes diffs impossible to read. Now I just set my editor to auto-format on save and never think about it again. Anyone else get roasted for little stuff like that early on?

Changed my mind about using notepad for coding after a workshop in Chicago

I always thought starting with a plain text editor was the way to learn, but someone at a free coding meetup in Chicago last month showed me how VS Code's color coding catches syntax errors instantly. Has anyone else had a simple tool like that save them hours of debugging?

Had to pick between Python and JavaScript for my first real project

I finally decided to build a proper project after 3 months of tutorials. I had this idea to make a tool that tracks my weekly spending and gives me a simple summary. I went back and forth between Python and JavaScript for about two weeks before settling on Python with just plain text files for storage. The hardest part was picking between Flask for a web interface or keeping it as a command line app. I ended up going with the command line version and honestly it took me about 4 evenings to get something working. Has anyone else struggled with picking a first language for a real project instead of just following tutorials?

Spent 3 hours debugging a missing semicolon in my first Python script

I was sitting at my kitchen table last Tuesday trying to follow along with a YouTube tutorial on loops. My code kept throwing a syntax error and I couldn't figure out why. After like 45 minutes of re-reading the tutorial and checking my indentation, I finally copied the whole thing into a fresh file. Turns out I had typed a semicolon at the end of a line from muscle memory with JavaScript. I literally laughed at myself for 2 minutes straight. Has anyone else gotten tripped up by mixing up syntax between languages they're learning?

Can we talk about how VS Code autocomplete ruined me for Notepad++?

I started learning Python 3 months ago using VS Code with all the fancy extensions. Last week I had to edit a config file on a remote server and only had Notepad++ available. I sat there for 5 minutes just staring at the screen waiting for autocomplete to kick in. It never did obviously. I had to type out every single bracket and comma by hand. That little experiment made me realize how much I lean on those crutches. Has anyone else felt completely lost when switching to a bare bones editor?

Just realized my friend Mike was right about learning Python slowly

I was trying to learn Python by jumping into big projects like a weather app and a game. My buddy Mike kept telling me to just do small exercises for 15 minutes a day instead. I thought that was too slow and would take forever to learn anything useful. After 3 weeks of struggling with my weather app and feeling totally lost, I finally tried his approach. I started doing those tiny problems on Edabit and Codecademy, like reversing strings and finding prime numbers. Turns out Mike was completely right because after 2 months of short daily practice, I can actually read and understand code way better now. Has anyone else had a friend give them advice that felt wrong but turned out to be golden?

Finally figured out console.log debugging in JavaScript lol

I've been learning JavaScript for about 2 months now and kept getting stuck on why my loops weren't working. My code looked fine to me but the output was all wrong. I tried reading tutorials and watching videos but nothing clicked. Then last night I just started throwing console.log statements everywhere in my code to see what values my variables actually had at each step. Turns out I was accidentally resetting a counter inside the loop without realizing it. I fixed it in like 5 minutes after that. Has anyone else had those moments where the simplest trick saves you hours of staring at the screen?

Switched from Visual Studio to VS Code for my first Python project

I was dead set on using Visual Studio for my first Python project because I figured more features = better. But after 3 days of waiting for it to load and getting lost in all the menus, I gave VS Code a try. A buddy in my coding group showed me how to install the Python extension in like 2 minutes. I finished my little calculator app in under 4 hours with way less frustration. Now I get why beginners keep saying to start simple. Has anyone else made a similar switch and regretted it or been glad they did?

Rant: Found out my code was exposing user emails for 6 months

I was digging through my server logs last night and discovered a stat that floored me - my first web app had been leaking user emails in the API responses since launch. A buddy who does pentesting in Austin pointed it out during a casual code review. Turns out I forgot to strip the email field from the JSON output on the user profile endpoint. 47 people had signed up in that time. Has anyone else found a scary bug like this way after the fact?

Finally stopped forgetting semicolons in JavaScript

Kept getting syntax errors for weeks. Turned out I was missing semicolons at the end of lines in a loop. Once I started adding them every single time my code ran clean. Anyone else have a dumb mistake that took way too long to figure out?

Dropped $150 on a Python bootcamp and it was basically just YouTube videos

Vent: My coworker told me I was overcomplicating CSS and I hated how right she was

So last week Sarah from the next desk looked at my 400 line stylesheet and asked why I had seperate classes for every single margin size. I got defensive at first because I thought I was being thorough and organized. But she pulled up her own project and showed me how she uses utility classes and it made so much sense. Honestly it hit different because I realized I was writing code that looked impressive but was actually a nightmare to maintain. She wasn't being mean about it just pointed out a simpler way. Now I'm going back through my old projects and refactoring everything. Has anyone else had that moment where someone half your experience shows you a better way to do something basic?

Just realized my mentor was wrong about learning frameworks too early

My first coding buddy, Chris, told me I needed to learn React before I even understood JavaScript loops. I spent 3 weeks struggling through a tutorial that made zero sense until I gave up and went back to basics. Turns out he was just repeating what some bootcamp taught him, not what actually works for beginners. Anyone else get bad advice from someone who sounded like they knew what they were talking about?

My buddy said to just use "while true" loops for everything and I crashed my laptop 6 times in one afternoon

He told me it was fine because infinite loops are "just a rite of passage" for beginners, but my fan sounded like a jet engine for 20 minutes straight before I realized I forgot a break condition. Has anyone else had a friend give them terrible coding advice that seemed smart at first?

That coding bootcamp meetup in Austin almost cost me my project

I went to a free coding workshop downtown Austin last month. The instructor told everyone to blindly copy-paste a huge block of jQuery from a shared drive. Two days later my whole portfolio site froze because it had a hidden loop that ate up memory. Has anyone else had a bad experience using code from random meetup groups?

Picked Python over JavaScript for my first language and here's what happened after 6 months

I spent like 3 weeks going back and forth on which coding language to start with. Everyone said JavaScript because it's everywhere, but Python kept calling to me because of the simpler syntax. I went with Python and after 6 months of night shifts I finally built a little script that automates part of my patient charting at work. It's not much but it saves me maybe 20 minutes per shift. Now I'm wondering if I should circle back to JavaScript or stick with Python deeper. Has anyone else picked a 'beginner' language and regretted or loved it later?

That guy who said beginners should skip Python and go straight to C++

I overheard someone at a meetup telling a newbie that Python is a waste of time and they should learn C++ first for "real programming." That advice ignores how most people learn best which is through quick wins and building things fast. How many beginners actually stick with coding after months of fighting memory management and segmentation faults before they can even make a simple app?

Hit 1000 lines on my very first Python script and it was completely useless

My first Django app crashed on deployment and I panicked for 2 hours

I built a simple blog app following a tutorial, but when I pushed it to Heroku, it just showed a blank white page. Turns out I forgot to set DEBUG=False and add allowed hosts. Has anyone else had a deployment fail over something this silly?
