noVoid (since v1.0.0)

Diagnostic Category: lint/complexity/noVoid

Sources:

Same as: no-void

Disallow the use of void operators, which is not a familiar operator.

The void operator is often used merely to obtain the undefined primitive value, usually using void(0) (which is equivalent to void 0). In these cases, the global variable undefined can be used.

Examples

Invalid

void 0;
