Q
How can you optimize SVG animations created with JavaScript for better performance?

Answer & Solution

Answer: Option B
Solution:
You can optimize SVG animations created with JavaScript for better performance by reducing the number of animated elements and avoiding complex animations whenever possible. Large numbers of animated elements or highly complex animations can lead to performance issues, especially on older devices or slower browsers. By prioritizing optimization techniques such as simplifying animations, minimizing DOM manipulation, and using efficient coding practices, developers can ensure smooth and responsive SVG animations that perform well across various devices and browsers.
