What function do you need to call to get the width of the screen? width() getWidth() screenWidth() getScreenWidth()

The function you need to call to get the width of the screen can vary depending on the programming language you are using.

For example, in JavaScript, you can use window.innerWidth to get the width of the screen.

In Java (Android), you can use DisplayMetrics displayMetrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); int width = displayMetrics.widthPixels;

In Swift (iOS), you can use let screenWidth = UIScreen.main.bounds.width

So, none of the options you provided are universally correct. It depends on the specific language and platform you are working with.
