Rule: no-unused-expression

Disallows unused expression statements.

Unused expressions are expression statements which are not assignments or function calls (and thus usually no-ops).

Rationale

Detects potential errors where an assignment or function call was intended. Also detects constructs such as new SomeClass(), where a constructor is used solely for its side effects, which is considered poor style.

Config

Not configurable.

Examples
