Why use a variable to store the random RGB colours, instead of just returning the result to the function?

//why do you use this variable to store the random RGB?
function randomRGB() {
  const color = `rgb( ${randomVal()}, ${randomVal()}, ${randomVal()} )`;
  return color;
};

//instead of just returning the value back to the function?
function randomRGB() {
 //value is returned to the function
  return `rgb( ${randomVal()}, ${randomVal()}, ${randomVal()} )`;
};

The lessons often do things with extra steps with the intent of more clearly illustrating what each step is doing. The fact that you're thinking of effective optimizing strategies is evidence of your learning progress and grasp of the material. Good job! :+1:

One you get into arrow functions, this can be optimized even further:

let randomRGB = () => `rgb( ${randomVal()}, ${randomVal()}, ${randomVal()})`;
