56533eb9ac21ba0edf2244d2 | Comparison with the Inequality Operator | 1 | https://scrimba.com/c/cdBm9Sr | 16787 | comparison-with-the-inequality-operator |
--description--
The inequality operator (!=
) is the opposite of the equality operator. It means not equal and returns false
where equality would return true
and vice versa. Like the equality operator, the inequality operator will convert data types of values while comparing.
Examples
1 != 2 // true
1 != "1" // false
1 != '1' // false
1 != true // false
0 != false // false
--instructions--
Add the inequality operator !=
in the if
statement so that the function will return the string Not Equal
when val
is not equivalent to 99
.
--hints--
testNotEqual(99)
should return the string Equal
assert(testNotEqual(99) === 'Equal');
testNotEqual("99")
should return the string Equal
assert(testNotEqual('99') === 'Equal');
testNotEqual(12)
should return the string Not Equal
assert(testNotEqual(12) === 'Not Equal');
testNotEqual("12")
should return the string Not Equal
assert(testNotEqual('12') === 'Not Equal');
testNotEqual("bob")
should return the string Not Equal
assert(testNotEqual('bob') === 'Not Equal');
You should use the !=
operator
assert(code.match(/(?!!==)!=/));
--seed--
--seed-contents--
// Setup
function testNotEqual(val) {
if (val) { // Change this line
return "Not Equal";
}
return "Equal";
}
testNotEqual(10);
--solutions--
function testNotEqual(val) {
if (val != 99) {
return "Not Equal";
}
return "Equal";
}
