Funktiomäärittely, known in English as function definition, is a fundamental concept in programming and mathematics. It refers to the process of declaring and describing a function. This typically involves specifying the function's name, its parameters (inputs), and the operations it performs to produce an output. A function definition serves as a blueprint for how a specific task or computation should be carried out.
In programming, a function definition provides the executable code that will run when the function is called.
