I have a question concerning using switch in a function.

Question

Soooo my question is why do I need to declare a local variable named "answer" with an empty string set as its value and then have a return statement at the end for answer? does this question make sense?

because when I omit the local variable and the return statement with "//" the code still works. I can assign caseInSwitch value to another variable and I can call on my function to show me that my code is running fine.

I dunno, if anyone can answer this great, if not..ill find out eventually.

function caseInSwitch(val) {
//var answer = "";

switch(val) {
case 1:
return "Nelson";
break;
case 2:
return "Nathaniel";
break;
case 3:
return "William";
break;
case 4:
return "Leroy";
break;
case 5:
return "Clyde";
break;
case 6:
return "Fanel";
break;
}
// return answer;
}

var storedName = caseInSwitch(1);

Answer 1

I believe its because I have return statements in my case statements. Im assuming thats why.
