56533eb9ac21ba0edf2244d3 | Comparison with the Strict Inequality Operator | 1 | https://scrimba.com/c/cKekkUy | 16791 | comparison-with-the-strict-inequality-operator |
--description--
The strict inequality operator (!==
) is the logical opposite of the strict equality operator. It means "Strictly Not Equal" and returns false
where strict equality would return true
and vice versa. Strict inequality will not convert data types.
Examples
3 !== 3
3 !== '3'
4 !== 3
In order, these expressions would evaluate to false
, true
, and true
.
--instructions--
Add the strict inequality operator to the if
statement so the function will return the string Not Equal
when val
is not strictly equal to 17
--hints--
testStrictNotEqual(17)
should return the string Equal
assert(testStrictNotEqual(17) === 'Equal');
testStrictNotEqual("17")
should return the string Not Equal
assert(testStrictNotEqual('17') === 'Not Equal');
testStrictNotEqual(12)
should return the string Not Equal
assert(testStrictNotEqual(12) === 'Not Equal');
testStrictNotEqual("bob")
should return the string Not Equal
assert(testStrictNotEqual('bob') === 'Not Equal');
You should use the !==
operator
assert(code.match(/(val\s*!==\s*\d+)|(\d+\s*!==\s*val)/g).length > 0);
--seed--
--seed-contents--
// Setup
function testStrictNotEqual(val) {
if (val) { // Change this line
return "Not Equal";
}
return "Equal";
}
testStrictNotEqual(10);
--solutions--
function testStrictNotEqual(val) {
if (val !== 17) {
return "Not Equal";
}
return "Equal";
}
