What are the performance differences between if-else and switch statements?

What are the performance differences between if-else and switch statements?

The performance can vary based on the context. Generally, if-else statements are more flexible, while switch statements can be faster for multiple conditions.

Can you explain why switch statements might be faster?

Switch statements can be optimized by the compiler to use jump tables, which allows for quicker access to the cases compared to evaluating each if condition sequentially.

Are there any scenarios where if-else is preferred over switch?

Yes, if-else is preferred when conditions are complex or not just simple equality checks, as it allows for more flexibility.

What about performance in large datasets?

In large datasets, switch statements can be more efficient if the cases are numerous and well-defined, but if-else can handle more complex logic.
