--description--
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:
var result = "";
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.
--instructions--
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.
--hints--
sequentialSizes(1)
should return "Low"
assert(sequentialSizes(1) === 'Low');
sequentialSizes(2)
should return "Low"
assert(sequentialSizes(2) === 'Low');
sequentialSizes(3)
should return "Low"
assert(sequentialSizes(3) === 'Low');
sequentialSizes(4)
should return "Mid"
assert(sequentialSizes(4) === 'Mid');
sequentialSizes(5)
should return "Mid"
assert(sequentialSizes(5) === 'Mid');
sequentialSizes(6)
should return "Mid"
assert(sequentialSizes(6) === 'Mid');
sequentialSizes(7)
should return "High"
assert(sequentialSizes(7) === 'High');
sequentialSizes(8)
should return "High"
assert(sequentialSizes(8) === 'High');
sequentialSizes(9)
should return "High"
assert(sequentialSizes(9) === 'High');
You should not use any if
or else
statements
assert(!/else/g.test(code) || !/if/g.test(code));
You should have nine case
statements
assert(code.match(/case/g).length === 9);
--seed--
--seed-contents--
function sequentialSizes(val) {
var answer = "";
// Only change code below this line
// Only change code above this line
return answer;
}
sequentialSizes(1);
--solutions--
function sequentialSizes(val) {
var answer = "";
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";
}
return answer;
}
