What are the best practices for using switch and if-else statements?

When using switch and if-else statements, it's important to keep your code readable and maintainable. Use switch for multiple discrete values and if-else for ranges or conditions.

Can you give me an example of when to use switch over if-else?

Sure! Use a switch statement when you have a variable that can take on multiple specific values, like days of the week. For example, switch(day) can handle 'Monday', 'Tuesday', etc., clearly.

What about performance? Is one better than the other?

In general, switch statements can be more efficient than if-else chains for many conditions, especially when dealing with a large number of cases. However, the difference is often negligible for small numbers.

Are there any common mistakes to avoid?

Yes! Common mistakes include forgetting to include a default case in switch statements and using complex conditions in if-else that can be simplified.
