How if Statements Determine Fullscreen Functionality in JavaScript

When developing rich web applications, offering users the option to view content in fullscreen mode can significantly enhance their experience. The Fullscreen API in JavaScript is a powerful tool that makes this possible by allowing web content to be presented over the entire screen.

However, enabling and managing fullscreen functionality requires careful logic and control structures, primarily utilizing if statements. Let's delve into how these conditional statements facilitate fullscreen functionality in JavaScript.

The Role of If Statements in Fullscreen Functionality

The primary role of if statements in the context of fullscreen functionality is to evaluate conditions and execute appropriate actions based on whether certain criteria are met. This ensures the application behaves as expected when toggling fullscreen mode.

Checking for Fullscreen Support

Before attempting to enter fullscreen mode, it's essential to check whether the browser supports the Fullscreen API. This is where an if statement comes into play:
