👉 In computer science, a "hook" is an instruction that operates on or modifies data at runtime. In other words, a hook can be executed after its function has been called, allowing for more efficient execution of code. For example, in Python, a hook is typically used to execute a function immediately before it is called, which allows the function's return value to be returned to the caller without needing to call another function. This optimization can improve performance and reduce memory usage compared to calling the function
