56533eb9ac21ba0edf2244d9 | Comparisons with the Logical Or Operator | 1 | https://scrimba.com/c/cEPrGTN | 16800 | comparisons-with-the-logical-or-operator |
--description--
The logical or operator (||
) returns true
if either of the operands is true
. Otherwise, it returns false
.
The logical or operator is composed of two pipe symbols: (||
). This can typically be found between your Backspace and Enter keys.
The pattern below should look familiar from prior waypoints:
if (num > 10) {
return "No";
}
if (num < 5) {
return "No";
}
return "Yes";
will return "Yes" only if num
is between 5
and 10
(5 and 10 included). The same logic can be written as:
if (num > 10 || num < 5) {
return "No";
}
return "Yes";
--instructions--
Combine the two if
statements into one statement which returns "Outside"
if val
is not between 10
and 20
, inclusive. Otherwise, return "Inside"
.
--hints--
You should use the ||
operator once
assert(code.match(/\|\|/g).length === 1);
You should only have one if
statement
assert(code.match(/if/g).length === 1);
testLogicalOr(0)
should return "Outside"
assert(testLogicalOr(0) === 'Outside');
testLogicalOr(9)
should return "Outside"
assert(testLogicalOr(9) === 'Outside');
testLogicalOr(10)
should return "Inside"
assert(testLogicalOr(10) === 'Inside');
testLogicalOr(15)
should return "Inside"
assert(testLogicalOr(15) === 'Inside');
testLogicalOr(19)
should return "Inside"
assert(testLogicalOr(19) === 'Inside');
testLogicalOr(20)
should return "Inside"
assert(testLogicalOr(20) === 'Inside');
testLogicalOr(21)
should return "Outside"
assert(testLogicalOr(21) === 'Outside');
testLogicalOr(25)
should return "Outside"
assert(testLogicalOr(25) === 'Outside');
