What is the primary use of the ng update command?

To add new features to the Angular project
To update Angular packages and dependencies to the latest compatible versions
To serve an application in a development environment
To remove outdated packages from the project

The correct answer is: To update Angular packages and dependencies to the latest compatible versions

The ng update command is primarily used to update Angular packages and dependencies to their latest compatible versions. This command is a part of the Angular CLI (Command Line Interface) and helps developers manage their Angular project’s dependencies effectively. It ensures that the installed packages are aligned with the latest features, improvements, and security patches without breaking any existing functionality in the application. When using ng update, the command also analyzes the package.json file and provides feedback on any necessary changes required to maintain compatibility between various Angular packages. This automated process simplifies dependency management significantly, especially as Angular continues to evolve and release new versions. Other options, while relevant to the Angular ecosystem, do not accurately describe the primary use of ng update. Adding new features might involve different commands or processes depending on the specific features being integrated. Serving an application typically utilizes the ng serve command, and removing outdated packages is managed through other npm commands rather than ng update.
