A developer needs to perform the same set of calculations at multiple points within an application. Which programming concept would be BEST to use to avoid writing the same code repeatedly?
Array
Loop
Variable
Function
The correct answer is a function. A function is a reusable block of code that performs a specific task and can be called multiple times from different parts of a program. Using a function improves code reusability, organization, and maintainability. A variable stores a single data value, an array stores a collection of elements, and a loop repeatedly executes code as long as a condition is met, but a function is the specific construct for creating a reusable, callable block of instructions.
