👉 A crosspatch in computer science refers to a method of modifying an object or data structure while keeping it unchanged. This is particularly useful when you want to modify the value of an existing object without affecting its state, but still preserve all other properties and methods of that object. For example: ```python class Person: def __init__(self): self.name = "John Doe" person = Person() # Modify the name property of the person object person.name = "Jane Doe"
