56533eb9ac21ba0edf2244dd Selecting from Many Options with Switch Statements 1 https://scrimba.com/c/c4mv4fm 18277 selecting-from-many-options-with-switch-statements

--description--

If you have many options to choose from, use a switch statement. A switch statement tests a value and can have many case statements which define various possible values. Statements are executed from the first matched case value until a break is encountered.

Here is an example of a switch statement:

switch(lowercaseLetter) {
  case "a":
    console.log("A");
    break;
  case "b":
    console.log("B");
    break;
}

case values are tested with strict equality (===). The break tells JavaScript to stop executing statements. If the break is omitted, the next statement will be executed.

--instructions--

Write a switch statement which tests val and sets answer for the following conditions:
1 - alpha
2 - beta
3 - gamma
4 - delta

--hints--

caseInSwitch(1) should have a value of the string alpha

assert(caseInSwitch(1) === 'alpha');

caseInSwitch(2) should have a value of the string beta

assert(caseInSwitch(2) === 'beta');

caseInSwitch(3) should have a value of the string gamma

assert(caseInSwitch(3) === 'gamma');

caseInSwitch(4) should have a value of the string delta

assert(caseInSwitch(4) === 'delta');

You should not use any if or else statements

assert(!/else/g.test(code) || !/if/g.test(code));

You should have at least 3 break statements

assert(code.match(/break/g).length > 2);

--seed--

--seed-contents--

function caseInSwitch(val) {
  let answer = "";
  // Only change code below this line



  // Only change code above this line
  return answer;
}

caseInSwitch(1);

--solutions--

function caseInSwitch(val) {
  let answer = "";

  switch(val) {
    case 1:
      answer = "alpha";
      break;
    case 2:
      answer = "beta";
      break;
    case 3:
      answer = "gamma";
      break;
    case 4:
      answer = "delta";
  }
  return answer;
}
