Angular Interview Practice

What is the purpose of the ng lint command?

1. Compiles the Angular application to JavaScript

2. Creates a new project

3. Checks the code for linting errors based on project configuration

4. Runs unit tests for the application

The correct answer is: Checks the code for linting errors based on project configuration

The purpose of the ng lint command is to check the code for linting errors based on the project's configuration. Linting is a process that analyzes code to identify potential errors, code style violations, and other issues that can affect code quality. By using ng lint, developers can maintain a consistent coding style and catch bugs early in the development process, enhancing overall code reliability and readability. Linting configurations can be customized within the project, allowing teams to enforce specific coding standards and practices. This can be particularly beneficial in larger projects or teams, where code consistency is crucial for collaboration and maintainability. Other choices relate to different functionalities of Angular, such as compiling the application, creating new projects, or running unit tests, but they do not pertain to the linting process that ng lint specifically addresses. Thus, ng lint serves a unique and essential role in the Angular development workflow by focusing on static code analysis for improving code quality.
