--description--
In a switch statement you may not be able to specify all possible values as case statements. Instead, you can add the default statement which will be executed if no matching case statements are found. Think of it like the final else statement in an if/else chain.
A default statement should be the last case.
switch (num) {
case value1:
statement1;
break;
case value2:
statement2;
break;
...
default:
defaultStatement;
break;
}
--instructions--
Write a switch statement to set answer for the following conditions:
a - apple
b - bird
c - cat
default - stuff
--hints--
switchOfStuff("a") should return the string apple
assert(switchOfStuff('a') === 'apple');
switchOfStuff("b") should return the string bird
assert(switchOfStuff('b') === 'bird');
switchOfStuff("c") should return the string cat
assert(switchOfStuff('c') === 'cat');
switchOfStuff("d") should return the string stuff
assert(switchOfStuff('d') === 'stuff');
switchOfStuff(4) should return the string stuff
assert(switchOfStuff(4) === 'stuff');
You should not use any if or else statements
assert(!/else/g.test(code) || !/if/g.test(code));
You should use a default statement
assert(switchOfStuff('string-to-trigger-default-case') === 'stuff');
You should have at least 3 break statements
assert(code.match(/break/g).length > 2);

function switchOfStuff(val) {
var answer = "";
// Only change code below this line
// Only change code above this line
return answer;
}
switchOfStuff(1);
--solutions--
function switchOfStuff(val) {
var answer = "";
switch(val) {
case "a":
answer = "apple";
break;
case "b":
answer = "bird";
break;
case "c":
answer = "cat";
break;
default:
answer = "stuff";
}
return answer;
