Logical expressions
- && or and for "and"
- || or or for "or"
- ! or not for "not"
The operators && and || can be used between literal values, identifiers, functions or expressions. If an expression can be interpreted as an assignment expression, it should be in parentheses. For example, string1 = "Hello " && string2 = "World!" is interpreted as an assignment expression for the identifier string1. A valid logical expression would be either (string1 = "Hello ") && (string2 = "World!") or string1 == "Hello " && string2 == "World!".
The operators ! and not can be followed directly by a literal value, an identifier or a function, or by an expression in parentheses.
