Best Practices and Interview Q&A

Workflow Best Practices

• Learn the command palette first; everything is there.
• Run code --upgrade-extensions after big upgrades.
• Commit .vscode/extensions.json so teams share tools.
• Keep extensions lean; uninstall unused ones.
• Use snippets for repetitive boilerplate.

Interview Q&A

Q: How does IntelliSense work in VS Code?

A: Language servers provide completions, diagnostics and navigation. VS Code talks to them over Language Server Protocol, keeping the editor generic and the per-language smarts pluggable.

Q: How would you set up automated builds?

A: Define tasks in tasks.json with a shell or npm command and a problemMatcher, then run them from the terminal or shortcut them as defaults.

Q: How do you debug a remote application?

A: Use Remote-SSH to open the server folder, and launch.json with the remote runtime, so breakpoints and watches work as if local.

Q: What is a dev container?

A: A Docker container defined in .devcontainer that carries the toolchain, porting the same environment to every machine.

Key Points

• Command palette and shortcuts drive speed.
• Language servers power editor intelligence.
• Tasks and snippets automate the dull parts.
• Remote development matches every deployment target.
