JavaScript Setup
Setting up your development environment for JS
Before you start coding, you need a comfortable environment that helps you write, test, and debug your code efficiently.
1. Code Editor: VS Code
Visual Studio Code is the industry standard for web development.
- Essential Extensions:
- ESLint: Catch syntax and logic errors as you type.
- Prettier: Automatically format your code for consistency.
- Live Server: Run a local server for your HTML/JS files to see changes instantly.
2. Browser: Chrome or Firefox
Modern browsers have powerful Developer Tools (Press F12 or Ctrl+Shift+I).
- Use the Console to test small snippets of code and debug errors.
- Use the Source tab for step-by-step debugging.
3. Runtime: Node.js
Even for frontend developers, Node.js is essential for running build tools (like Vite, Webpack) and managing packages via npm/pnpm.
- Download from nodejs.org.
4. Global VS Local Setup
- For small tests: Use the Browser Console or a service like CodeSandbox or StackBlitz.
- For real projects: Set up a local repository with a build tool like Vite.
