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