Basic JavaScript: Selecting from Many Options with Switch Statements

JavaScript

Why is this code wrong if the insturctions tell you to use strict equality ===. I have seen some solutions and they did not use strict equality. Thank you.

function caseInSwitch(val) {
  var answer = "";
  // Only change code below this line
  switch(val) {
  case val === 1:
  return "alpha";
  break;
  switch(val)
  case val === 2:
  return "beta";
  break;
  switch(val)
  case val === 3:
  return "gamma";
  break;
  switch(val)
  case val === 4;
  return "delta"
  break;

  }

  
  // Only change code above this line  
  return answer;  


// Change this value to test
caseInSwitch(1);

#1. Wrong use of switch
Switch syntax works like this

switch(expr) {
    case expr:
        statements
        break or return
    case expr:
        statements
        breark or return
    ...
}

#2 You don’t need both return and break.
Return already exits from the function.

#3 Where is your closing bracelet for the function?

The case 1 answer needs to equal “alpha” in order for the code to execute. Case 2 answer needs to equal “beta” in order for the code to execute – etc. etc. etc.

Yeah, this challenge is driving me bananas as well, my code looks quite similar to yours, I’ve tried following gunhoo93’s layout/syntax but I feel like there’s some little thing that I’m not seeing.

function caseInSwitch(val) {
var answer = “”;
// Only change code below this line

switch(val) {
case 1:
“alpha”;
break;
case 2 :
“beta”;
break;
case 3 :
“gamma”;
break;
case 4 :
“delta”;
break;}
// Only change code above this line
return answer;
}

// Change this value to test
caseInSwitch(1);

syntax seems right but you are never assigning the answer

Ahhh, got it, thanks guys, I thought that was just a part of the operation like the return, this is why I ought not take extended coding breaks! Gracias!

Did everything except add this around the code:

switch(val) {

}

thats why it didn’t pass. sigh
