----
-
-Unlike the `and` and `or` operators, the `not` operator always returns a boolean value.
-
-```go-html-template
-{{ not true }} → false
-{{ not false }} → true
-
-{{ not 1 }} → false
-{{ not 0 }} → true
-
-{{ not "x" }} → false
-{{ not "" }} → true
-```
-
-Use the `not` operator, twice in succession, to cast any value to a boolean value. For example:
-
-```go-html-template
-{{ 42 | not | not }} → true
-{{ "" | not | not }} → false
-```
