  • Browser DevTools: Use console.log() to trace variables, or use breakpoints in Chrome/Firefox DevTools to pause and inspect values.
  • Debugger Statement: Insert debugger; in your code. It’ll pause execution if DevTools are open.
  • Error Handling: Use try-catch for catching runtime errors.
  • Linters: Tools like ESLint can help catch common mistakes before runtime.
  • Source Maps: If using bundlers like Webpack, enable source maps to debug your original code.
