Performance Tips

Too many extensions slow down VS Code. Keep it fast:

• Disable unused extensions - right-click → Disable
• Use workspace-specific extensions - enable per-project, not globally
• Check startup time: Help → Toggle Developer Tools → Performance tab
• Limit file watchers - add large folders to files.watcherExclude
• Keep VS Code updated - performance improves with each release

Common Mistakes

1. Installing too many extensions - 15-20 active extensions is ideal
2. Not configuring Prettier + ESLint - they need to work together
3. Ignoring keyboard shortcuts - learn 10 shortcuts, save hours
4. Not using multi-cursor - Ctrl+D is your best friend
5. Skipping settings sync - turn on Settings Sync to keep preferences across machines
6. Not using the integrated terminal - stop switching to a separate terminal app
