Immutable Copy

The term “immutable” is used to describe something that cannot be changed or altered. In various contexts, it refers to the inability of an object or data to be modified after it has been created.

An “immutable copy” typically refers to a copy of an object or data structure that retains the immutability characteristics of the original. In other words, when you create an immutable copy of something, you create a new instance that cannot be modified, just like the original.

This concept is commonly used in programming and data management to ensure that data remains unchanged when you need to create a new version of it, perhaps with some modifications. Immutable copies are often used for data sharing, functional programming, and to maintain the integrity of data.
