--description--
If you need to match one value against many options, you can use a switch statement. A switch
statement compares the value to the case statements which define various possible values. Any valid JavaScript statements can be executed inside a case block and will run from the first matched case
value until a break
is encountered.
Here is an example of a switch
statement:
switch (fruit) {
case "apple":
console.log("The fruit is an apple");
break;
case "orange":
console.log("The fruit is an orange");
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(__helpers.removeJSComments(code)) || !/if/g.test(__helpers.removeJSComments(code)));
You should have at least 3 break
statements
assert(__helpers.removeJSComments(code).match(/break/g).length > 2);

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;
}
