What is the default speed of animations in CodeHS if not explicitly set?

The default speed of animations in CodeHS is set to 60 frames per second. This high frame rate is commonly used in many applications and games as it provides smooth and fluid motion, allowing for a more visually appealing user experience. A frame rate of 60 frames per second means that the animation refreshes 60 times each second, which is generally sufficient to create the illusion of continuous movement for the human eye. Understanding this concept is vital for creating effective animations, as it helps developers control the pacing and fluidity of animated sequences within their projects.

The other options reflect frame rates that may be used in different contexts or applications but do not apply as the default setting in CodeHS. For example, 30 frames per second is often considered standard for older televisions or films, while 24 frames per second is a common rate for cinematic content, and 120 frames per second is used in high-refresh-rate gaming but is not the default in CodeHS.
