JS Ternary functions with multiple conditions?

Question

I have been using a ternary operator in JavaScript to modify the value of an object based on user input. I have the following code, which runs as it should:

Answer 1

A switch statement is likely the best choice in a situation like this.

let inputOneAns;
switch(inputOne) {
  case "Yes":
   inputOneAns = "517";
   break;
  case "No":
   inputOneNas = "518";
   break;
  default:
   inputOneNas = "";
}

If you could do ternary operations beyond 2 conditions, they would become incredibly messy. You can put conditions together, but I've no idea why you would want that - that would be incredibly messy.
