How can you play a sound effect in a CodeHS game?

Using the playSound("soundfile.mp3") function is the correct method to play a sound effect in a CodeHS game because it directly utilizes the built-in sound management system provided by the platform. This function takes the name of the sound file as a parameter, indicating which sound to play, and ensures that the sound is rendered appropriately within the game environment.

The function is designed to handle both the loading and playback of sound files, which makes it a simple and effective way to enhance the gaming experience through auditory feedback and atmosphere. By specifying the filename in the correct format, the function ensures the sound file is located and played at the right moment in your game's execution.

Other methods, such as invoking sound, calling play, or using listenToSound, do not correspond to the officially supported functions within the CodeHS framework for sound playback, which is why they would not successfully play a sound effect as intended.
