What are the performance differences between anonymous and named functions?

What are the performance differences between anonymous and named functions?

Named functions are generally more performant than anonymous functions due to better optimization by JavaScript engines.

Can you explain why named functions are more optimized?

Named functions can be optimized better because they have a fixed reference, allowing engines to perform more efficient inlining.

Are there any scenarios where anonymous functions are preferred?

Yes, anonymous functions are often preferred in callbacks or when creating closures, as they can be defined inline.

What about readability? Does it affect performance?

Readability doesn't directly affect performance, but using named functions can improve code clarity, making maintenance easier.
