Q
What role does event delegation play in handling SVG animations with JavaScript?

Answer & Solution

Answer: Option C
Solution:
Event delegation in handling SVG animations with JavaScript manages interactions for multiple SVG elements using a single event listener. Instead of attaching separate event listeners to each SVG element, event delegation assigns a single event listener to a parent container or the document itself and then delegates event handling based on the target element. This approach optimizes performance, reduces event handling overhead, and simplifies code management for handling interactions in SVG animations involving multiple elements.
