!=
) 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
!=
in the if
statement so that the function will return "Not Equal" when val
is not equivalent to 99
testNotEqual(99)
should return "Equal"
testString: assert(testNotEqual(99) === "Equal", 'testNotEqual(99)
should return "Equal"');
- text: testNotEqual("99")
should return "Equal"
testString: assert(testNotEqual("99") === "Equal", 'testNotEqual("99")
should return "Equal"');
- text: testNotEqual(12)
should return "Not Equal"
testString: assert(testNotEqual(12) === "Not Equal", 'testNotEqual(12)
should return "Not Equal"');
- text: testNotEqual("12")
should return "Not Equal"
testString: assert(testNotEqual("12") === "Not Equal", 'testNotEqual("12")
should return "Not Equal"');
- text: testNotEqual("bob")
should return "Not Equal"
testString: assert(testNotEqual("bob") === "Not Equal", 'testNotEqual("bob")
should return "Not Equal"');
- text: You should use the !=
operator
testString: assert(code.match(/(?!!==)!=/), 'You should use the !=
operator');
