RedundantBooleanExpression

Severity: Medium | Category: Security

Detects redundant or duplicated operands in boolean expressions.

Why is it bad?

Duplicate conditions add no logical value, waste computation, and may indicate copy-paste errors or logic mistakes.

Example

// Bad: (self.a == 0) is checked twice
return (self.a == 0) || (self.a == 0);

Use instead:

// Fix: Remove the duplicate
return (self.a == 0);
