Frequently Asked Questions

Do VS Code extensions slow down the editor?

Some extensions do have a performance impact, especially if you install dozens of them. The extensions in this list are all well-optimised and have minimal impact individually. If you notice VS Code slowing down, use the built-in startup performance tool — press Ctrl+Shift+P and type Startup Performance — to identify which extensions are taking the longest to load.

Are VS Code extensions free?

The vast majority of VS Code extensions are completely free. GitHub Copilot is the main exception on this list, requiring a $10/month subscription after a free trial.

Can I sync my VS Code extensions across computers?

Yes. VS Code has built-in Settings Sync — sign in with your GitHub or Microsoft account and your extensions, settings, keybindings, and snippets are automatically synced across every machine.

Which extensions are must-have for JavaScript developers?

Prettier, ESLint, Error Lens, GitHub Copilot, GitLens, and Path Intellisense are the essential six for any JavaScript or TypeScript developer.

How many VS Code extensions should I install?

Install only what you actively use. A focused set of 10 to 15 high-quality extensions is more valuable than 50 extensions you rarely use. Start with the essentials from this list and add more as specific needs arise.
