Description: A helper function is an essential component in programming that is responsible for performing specific tasks to support other functions or methods. These functions are designed to be reusable, meaning they can be invoked multiple times from different parts of the code, reducing redundancy and improving code readability. By breaking the code into smaller, manageable functions, understanding and maintaining the software becomes easier. Helper functions typically handle tasks such as data validation, string formatting, mathematical calculations, or data structure manipulation. Their use not only optimizes code performance but also allows developers to focus on the main logic of the application, delegating specific tasks to these functions. In summary, helper functions are a key tool in code refactoring, promoting modularity and clarity in software development.
