I'm building a function which gets a variable that includes a mathematic operator, and two random numbers. I want to return the result of the suitable math action, but I'm not sure how the code should be written.

function result(firstnum, secnum, operator) {
return [???];
}

Create an object that maps operator names to functions, then call the function. – Barmar May 22 '18 at 20:58

`return operators[operator](firstnum, secnum);` – Barmar May 22 '18 at 20:59
