👉 Pre-advance is a technique used in computer science and programming to optimize code by adding variables or functions that are not required at runtime. This can be achieved through using global variables, which are created once globally and then deleted after use, or by creating local variables within each function they are called in. In the context of pre-advancement, it means the process of creating a variable before its actual usage (i.e., when it is first defined) to save memory. This can be useful
