--description--
Sometimes you will need to test more than one thing at a time. The logical and operator (&&
) returns true
if and only if the operands to the left and right of it are true.
The same effect could be achieved by nesting an if
statement inside another if
.
if (num > 5) {
if (num < 10) {
return "Yes";
}
}
return "No";
This code will return Yes
if num
is greater than 5
and less than 10
. The same logic can be written with the logical and operator.
if (num > 5 && num < 10) {
return "Yes";
}
return "No";
--instructions--
Replace the two if statements with one statement, using the &&
operator, which will return the string Yes
if val
is less than or equal to 50
and greater than or equal to 25
. Otherwise, will return the string No
.
--hints--
You should use the &&
operator once
assert(__helpers.removeJSComments(code).match(/&&/g).length === 1);
You should only have one if
statement
assert(__helpers.removeJSComments(code).match(/if/g).length === 1);
testLogicalAnd(0)
should return the string No
assert(testLogicalAnd(0) === 'No');
testLogicalAnd(24)
should return the string No
assert(testLogicalAnd(24) === 'No');
testLogicalAnd(25)
should return the string Yes
assert(testLogicalAnd(25) === 'Yes');
testLogicalAnd(30)
should return the string Yes
assert(testLogicalAnd(30) === 'Yes');
testLogicalAnd(50)
should return the string Yes
assert(testLogicalAnd(50) === 'Yes');
testLogicalAnd(51)
should return the string No
assert(testLogicalAnd(51) === 'No');
testLogicalAnd(75)
should return the string No
assert(testLogicalAnd(75) === 'No');
testLogicalAnd(80)
should return the string No
assert(testLogicalAnd(80) === 'No');
