What is the primary benefit of hot reloading in Backstage development?

It runs the test suite automatically after every code change.

It reflects code changes in the browser without requiring a manual page refresh.

It automatically restarts the entire application when code changes are saved.

It compiles the code into a production bundle for faster execution.

How does Backstage handle environment-specific configuration, such as different settings for local development versus production?

By requiring a separate codebase for each environment.

By using a single configuration file that is the same for all environments.

By using environment variables and configuration files that can be overridden per environment.

By hardcoding all configuration values in the source code.

What is the purpose of using `console.log` statements during local debugging of a Backstage application?

To automatically fix bugs in the code.

To compile the code into a production bundle.

To output diagnostic information to the browser console or terminal.

A developer is working on a Backstage plugin and modifies a TypeScript file in the plugin's `src` directory. The dev server is running, but the change does not appear in the browser. The terminal shows a compilation error. What should the developer do first?

Run `yarn build` to compile the plugin and then refresh the browser.

Restart the dev server to force a fresh compilation.

Fix the compilation error in the TypeScript file and save it again.

Clear the browser cache and refresh the page.
