Setting Up a JavaScript Course Isn't as Bad as People Think
The biggest bottleneck I see when people start a JavaScript course is tooling paralysis. They spend three days debating between WebStorm and VS Code, second-guessing their Node version, and reading conflicting stack overflow threads about whether they need nvm or volta or some other version manager nobody asked for. By the time they actually write a line of code, they've burned a whole weekend. Here's what actually works. Keep it boring. Install Node 20 LTS from the official website — not a PPA, not a snap package, just the installer from nodejs.org. You can verify it with node -v and npm -v. If those return sensible versions, you're already past the point where most people get stuck.
Setup Guide For JavaScript Course
Pick one editor. I use VS Code because it's free and gets updated weekly. The extensions that matter are ESLint, Prettier, and maybe Live Server if you're doing browser-side work. That's it. Any more than that and you're curating a toolkit instead of learning JavaScript. Create your project folder, run npm init -y from inside it, then install dev dependencies: npm install --save-dev eslint prettier. Set up a basic .eslintrc.json with the recommended rules and a .prettierrc with single quotes and semi-colons. Don't overthink the config. It'll save you from arguing with yourself about style later. One thing nobody tells you about setting up a JS course: the DOM doesn't care about your build toolchain. If your curriculum covers browser JavaScript early on, skip bundlers entirely for the first few weeks. Just serve files with npx serve or a literal two-line Python http server. Webpack, Vite, esbuild — they're useful. They're not useful when you're trying to understand how document.querySelector actually works and you spend two hours debugging a sourcemap issue that has nothing to do with the material you're studying.
I ran into this exact problem last year when someone on my team was setting up a course for junior developers. We had Vite configured, TypeScript, ESLint with strict mode, the whole nine yards. The students spent more time fighting configuration errors than learning anything about closures or event loops. I stripped it all back to bare Node with plain .js files served through a static folder. Productivity jumped immediately. They were writing actual code within an hour instead of spending three sessions on environment setup. For course structure, organize your repository so each lesson is its own directory with an index.html, a script.js, and a README.md that explains the exercise. Put a shared package.json at the root for global dependencies. This way students can clone the repo and jump straight into any lesson without guessing which folder they're supposed to be in. Testing is where most courses go wrong. Don't throw Jest at beginners on day one. Start with simple console assertions — console.assert actually works fine for basic validation — then graduate to a lightweight runner likeAVA or Jest once they understand what they're testing. I've seen too many people memorize test syntax without understanding why the test matters, which defeats the whole purpose.

Also, and this is counter-intuitive: teach async/await before callbacks. Not because callbacks are obsolete — they're not — but because modern JavaScript codebases use promises and async patterns almost exclusively. Students who learn the callback pyramid first often struggle to unlearn that mental model. Start with fetch examples or setTimeout wrapped in Promises, show them the pattern, then introduce async/await as syntactic sugar. They'll pick up callbacks later naturally when they hit legacy code. The main downside to keeping setup minimal is that students won't encounter real-world build tooling until much later. If your course is meant to prepare them for enterprise environments, you'll need to introduce module bundlers and transpilers somewhere in the second half. But introducing them too early is worse than introducing them too late. At least when they see Vite later, they'll understand what problem it's actually solving instead of treating it like magic. For hosting or sharing the course materials, GitHub Pages works fine for static content. Push your lesson folders and enable Pages from the repository settings. It takes about five minutes and gives you a live URL where students can see their browser-based exercises running. No hosting fees, no configuration drift, no server to maintain.
One last thing about version control for course projects: commit at meaningful points, not after every typo fix. A clean commit history makes it easier for students to follow along and for you to reference specific lessons. Use conventional commit messages if you want to keep it simple — just prefix with feat:, fix:, or docs: and you're done. Set up a .gitignore file early. node_modules, .env, dist folders, any build artifacts. I've seen students accidentally commit their entire dependency tree and blow up repository size to hundreds of megabytes. It's embarrassing and hard to undo cleanly. That's really all there is to it. A working Node installation, a text editor, a Git repository, and the discipline to start writing code instead of tweaking the environment forever.
