What does the command ng build --prod do?

Runs the application in development mode
Builds the application with production optimizations
Generates a new production server
Prepares the application for testing

The correct answer is: Builds the application with production optimizations

The command ng build --prod is used to build an Angular application with production optimizations, resulting in a highly optimized set of output files for deployment. When this command is executed, several important optimizations take place, including: 1. **Tree Shaking**: Unused modules and code are eliminated from the final bundle, which reduces the size of the application. 2. **Ahead-of-Time (AOT) Compilation**: The Angular templates are compiled during the build process rather than at runtime, which not only improves performance but also helps catch template errors early. 3. **Minification**: The JavaScript and CSS files are minified, which further decreases the file sizes by removing whitespace and comments, making the application faster to load. 4. **Uglification**: Variable names and other identifiers in the code are shortened, which also contributes to reducing file sizes. Overall, using the ng build --prod command enables developers to prepare an Angular application for production, ensuring it is efficient and optimized to deliver the best performance to end users. This process also enhances security and improves load times, making it essential for deploying an application in a real-world environment.
