- ↑ The empty operator is a prefix operation that can be used to determine whether a value is null or empty.
- ↑ Comparisons can be made against other values, or against boolean, string, integer, or floating point literals.
- ↑ Evaluate B or C, depending on the result of the evaluation of A.
The precedence of operators highest to lowest, left to right is as follows:
- [] .
- () - Used to change the precedence of operators.
- - (unary) not ! empty
