Here are the most important Logical Operators summarized in a table.

|
Logical Operators can be used for conditions as they show a result in form of a `boolean` (True/False) or Unknown.
|
|
So, e.g. if an exact value is `True` for a value, a Logical Operator can proof that it's True.

| ANY | If any comparison is True: return True |
|
|
| AND | If both expressions are True: return True |
|
|
