Functions

The role of functions

Functions allow you to perform specific operations on different types of data, such as numbers, strings, dates, and arrays. By using functions, you can modify, extract, or combine information to meet your needs.

Each function has a set of parameters that determine its behavior. These parameters specify the data on which the function should act, as well as other options or configurations necessary for the operation. Once the parameters are provided, the function performs its action and returns a result.

It is important to note that functions can vary depending on the type and structure of the data on which they are applied. For example, a specific function may not work on a number but may be applicable to a string. Therefore, it is essential to understand the available functions and the types of data they accept in order to use them correctly.
