What method is used to check for user input through the keyboard in CodeHS?

The method utilized to check for user input through the keyboard in CodeHS is keyPressed(). This function is designed to detect whether a specific key is currently being pressed down. When implemented in a program, it can be used in conjunction with other functions or in event handling to create responsive actions based on the user's keyboard interactions.

Using keyPressed() allows you to execute different code blocks based on the key input, enabling dynamic control over animations, game actions, or other interactive elements. This method is particularly useful in creating engaging and interactive applications where user input plays a critical role.

The other options do not directly correspond to the established methods for keyboard input in CodeHS. For example, isKeyPressed() and checkKey() do not exist as recognized functions, while keyDown() may suggest an action but isn't the correct terminology used in this context. Thus, keyPressed() is the appropriate and correct choice for detecting keyboard input.
