Using Extract Function

Extract Function is a refactoring technique that helps to improve code readability and maintainability by breaking down a large or complex function into smaller, more manageable parts.

Let’s say you come across a function that’s performing multiple tasks. Maybe it’s doing some data validation, then some computations, and finally logging the result or updating some state. The function is long and complex, making it hard to understand at a glance what it’s doing. Extract Function refactoring is all about identifying those distinct pieces of functionality, pulling them out into their own separate functions, and then calling those new functions from the original one.

One key benefit is that it makes the code more self-documenting. If you extract a part of your function to a new function and give it a meaningful name, it can often make the code much easier to understand since the function name can describe what the code is doing....
