The inequality operator should be preferred over negating the equality comparison result

This rule applies when the logical negation operator is used on the equality comparison result.

The inequality operator (!==, !=) gives the same result as applying the negation operator (!) to the equality (===, ==) comparison result. Therefore, it is recommended to use the inequality operator because it is simpler and easier to understand.

Noncompliant Code Example

if (!(a === b)) { // PREFER_INEQUALITY_OPERATOR alarm
    doSomething(a);
}

Compliant Code Example

if (a !== b) {
    doSomething(a);
}
