Multiple Identical Options in Switch Statements

Multiple Identical Options in Switch Statements

Problem Explanation

If the break statement is omitted from a switch statement's case, the following case statement(s) are executed until a break is encountered. If you have multiple inputs with the same output, you can represent them in a switch statement like this:

switch(val) {
  case 1:
  case 2:
  case 3:
    result = "1, 2, or 3";
    break;
  case 4:
    result = "4 alone";
}

Cases for 1, 2, and 3 will all produce the same result.

Write a switch statement to set answer for the following ranges: 1-3- "Low"
4-6- "Mid"
7-9- "High"

Note: You will need to have a case statement for each number in the range.

Spoiler alert!

Solution ahead!

Code Solution:

function sequentialSizes(val) {
  var answer = "";
  // Only change code below this line
  switch(val) {
    case 1:
    case 2:
    case 3:
      return "Low";
      break;
    case 4:
    case 5:
    case 6:
      return "Mid";
      break;
    case 7:
    case 8:
    case 9:
      return "High";
      break;
  } 
  // Only change code above this line  
  return answer;  
}
// Change this value to test
sequentialSizes(1);

Alternative code solution:

function sequentialSizes(val) {
  var answer = "";
  // Only change code below this line
  switch(val){
    case 1: case 2: case 3:
      answer = "Low";
      break;
    case 4: case 5: case 6:
      answer = "Mid";
      break;
    case 7: case 8: case 9:
      answer = "High";
  }
  // Only change code above this line  
  return answer;  
}
// Change this value to test
sequentialSizes(1);

Code explanation

Since you already have a variable named answer defined and the function returns it, you can just modify its value on each group of case statements to fit the exercise requirements.
