In FP, a function takes inputs and produces output with the guarantee that the same inputs will yield the same outputs. In order to do this, a function must always have parameters for the values it operates on and cannot rely on state. Ie, if a function relies on state, and that state changes, the output of the function could be different. flow wall laundry set
