JavaScript Advanced

My working repo for JavaScript Advanced on shipthatcode.com — built lesson by lesson in my own editor.

What you need

• git and a terminal (macOS/Linux: the built-in one; Windows: see below)
• Node.js 18+ (node --version should work)
• any editor you like — VS Code, Vim, JetBrains, anything

On Windows

Use WSL if you can: run wsl --install in an admin PowerShell once, then do everything (git, editing, ./run_tests.sh) inside the Ubuntu terminal — it behaves exactly like the grader.

Git Bash (installs with git) also runs ./run_tests.sh. One caveat: native Windows compilers and runtimes write Windows line endings (\r\n), so on byte-exact tests you can see local FAILs where the diff looks identical — your logic is fine, the invisible line endings differ. If that happens, trust Check my solution on the lesson page (graded on Linux), or switch to WSL.

Getting started (one-time setup)

1. Unzip this download and open the folder in your editor.

2. Create a new empty, public repo at github.com/new — leave "Add a README" and ".gitignore" unchecked (this folder already has both).

3. In your terminal, inside the unzipped folder, push it to GitHub:

   git init
   git add .
   git commit -m "start JavaScript Advanced"
   git branch -M main
   git remote add origin https://github.com/YOUR-USERNAME/YOUR-REPO.git
   git push -u origin main

4. Paste your repo link on the course page ("Work in your own editor" → Link repo). Done — you never do this again.

The lesson loop

1. Read the lesson on shipthatcode, write your code in main.js here.
2. Test locally: ./run_tests.sh 01 (lesson 01's tests) or ./run_tests.sh (everything). On Windows, run this inside Git Bash.
3. When it passes: git add -A && git commit -m "lesson 01" && git push
4. Hit Check my solution on the lesson page — shipthatcode pulls this repo and grades it against the full suite, including hidden tests.

How this repo is laid out

• main.js — the program. It grows as the course progresses; each lesson adds to it.
• tests/ — the public test cases per lesson (tests/01-…/1.in → expected 1.out).
• run_tests.sh — the local runner. .shipthatcode.json tells the grader what this repo is; don't delete either.
