👉 In the context of computer science, "copier" is a function in programming languages that copies data from one memory location to another. It's often used when you need to copy values between two different types of memory locations (e.g., an array and a linked list). This operation can be useful for managing memory efficiently by allowing you to store data without needing to allocate new space for each element in the list or array, which can lead to significant performance improvements.
