Partial Functions in Scala

In Scala, partial functions are implemented using the PartialFunction trait. Partial functions are functions that are defined only for certain input values and are undefined for others.

Partial functions in Scala have several advantages over total functions:

• Partial functions can provide more flexibility in handling different input values, allowing for specific logic to be applied only for certain cases.
• Partial functions can help in improving code readability by clearly defining the behavior for specific input values.
• Partial functions can be used to handle exceptional cases or edge cases in a more structured way.

Overall, partial functions in Scala can be a powerful tool for writing expressive and concise code that effectively handles different cases and scenarios.
