Description: A function in programming is a declaration that specifies the name, parameters, and body of the function. Functions are essential for performing calculations and transformations on data. They allow users to manipulate and analyze information effectively, facilitating the creation of graphs, reports, and alerts based on specific conditions. Functions can be simple, such as summing or averaging values, or more complex, such as applying filters or logical conditions. Each function has a defined purpose and can receive one or more parameters, which are the data on which the operation will be applied. The correct definition and use of functions is crucial for optimizing performance and ensuring that accurate and useful insights are obtained from data. Additionally, functions can be customized, allowing users to tailor algorithms to the specific needs of their applications and business objectives.
