SuspiciousUnary

Severity: Low | Category: Security

A detector that highlights unusual unary expressions that look like a typo.

Why is it bad?

Having unary expressions such as x =+ 1 or return + 1; is probably a typo. Most likely, the developer intended to use a binary operation in that case and forgot the left-hand side expression.

Example

a =+ 1; // Suspicious

Use instead:

a += 1; // Fixed
