What is a common way to improve the performance of animations in CodeHS?

Improving the performance of animations often involves managing the resources used by your application effectively. Limiting the number of active sprites on the canvas is a proven strategy for enhancing performance. Each sprite requires computational resources for updating and rendering on the screen. When too many sprites are active simultaneously, it can lead to slower performance and choppy animations because the system struggles to keep up with rendering everything efficiently.

By reducing the number of active sprites, you can free up processing power and memory, allowing the remaining sprites to be rendered more smoothly. This can enhance the overall visual experience and make the animation more responsive to user interactions.

Adjusting sprite colors dynamically, increasing the frame rate, or adding sound effects to every frame can make the animation look or sound better, but they do not address the core issue of performance in the same way that managing sprite count does. High frame rates can also increase the workload on the system, potentially leading to performance issues rather than alleviating them.
