noVoid

Diagnostic Category: lint/complexity/noVoid

JavaScript (and super languages)

Since: v1.0.0 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;
