What are some common mistakes when using switch and if-else statements?

What are some common mistakes when using switch and if-else statements?

Some common mistakes include not using break statements in switch cases, leading to fall-through, and using complex conditions in if-else.

Can you explain what fall-through means in switch statements?

Fall-through occurs when a switch case does not have a break statement, causing the execution to continue into the next case.

What are the best practices to avoid these mistakes?

Best practices include always using break statements, keeping cases simple, and using if-else for complex conditions.

Are there any performance differences between switch and if-else?

Yes, switch statements can be more efficient for multiple discrete values, while if-else is better for complex conditions.
