# Description

Use the there is no operator to make sure an object or file does not yet exist before creating it, or that a program is not already running before launching it.

The there is no operator is the logical inverse of the there is a operator. When one is true, the other is false.

>*Note:* The there is no operator is implemented internally as a > function, and therefore has lower precedence than other > operators.
