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:

var inputOneAns = inputOne == "Yes" ? "517" : "518"; 

As you can see, I am assigning a numeric string value to inputOneAnswhether a user has inputed "Yes" or "No". However, there may be a case that a user has not selected a value (as it is not required). If this input was left blank, I would like to assign an empty string "" to inputOneAns. Is there a wayf or me to embed an ternary operator inside of another ternary operator? To help clarify, here is the same function that I want to accompolish with my ternary function but with if else statements?

if (inputOne == "Yes"){     var inputOneAns = "517" }else if (inputOne == "No"{     var inputOneAns = "518" }else{     var inputOneAns = "" } 

Is it possible to include multiple expressions into a ternary function? Is there a better way to accomplish what I am looking for? Thanks for the tips in advance.

Yes you can go wild nesting ternaries. I find this version to be fairly readable:

var foo = (   bar === 'a' ? 1 : // if    bar === 'b' ? 2 : // else if    bar === 'c' ? 3 : // else if   null // else  ); 

but that's not a widely shared opinion, and you should probably stick to if/else or switch when working on a team.
