Angular Interview Practice

What command would you use to build an Angular project for production?

1. ng build

2. ng build --release

3. ng build --prod

4. ng prod build

The correct answer is: ng build --prod

The command used to build an Angular project for production is "ng build --prod". This command instructs the Angular CLI to create a production-ready build, which includes optimizations such as ahead-of-time (AOT) compilation, tree shaking, and minification of assets. When building for production, these optimizations are crucial as they help reduce the application size, improve load times, and enhance overall performance. This is particularly important for real-world applications where performance and user experience are critical. The other commands do not provide the full set of production optimizations. For example, "ng build" on its own creates a development build that lacks various performance enhancements. Meanwhile, "ng build --release" is outdated and not applicable in recent versions of Angular, as the recommended way to achieve a release build is through the "--prod" flag. Lastly, "ng prod build" is not a valid command, as the syntax does not conform to the Angular CLI conventions.
