Order of Precedence of Operators
================================
The following is the order of precedence for operators, listed in order of evaluation.
+------------+-------------------------------------+--------------------------------------------+
| Precedence | Description | Operator |
+============+=====================================+============================================+
| *1* | Postfix increment and decrement | ``++``, ``--`` |
+ +-------------------------------------+--------------------------------------------+
| | Function-like call | ``<func>(<args...>)`` |
+ +-------------------------------------+--------------------------------------------+
| | Array subscripting | ``<array>[<index>]`` |
+ +-------------------------------------+--------------------------------------------+
| | Member access | ``<object>.<member>`` |
+ +-------------------------------------+--------------------------------------------+
| | Parentheses | ``(<statement>)`` |
+------------+-------------------------------------+--------------------------------------------+
| *2* | Prefix increment and decrement | ``++``, ``--`` |
+ +-------------------------------------+--------------------------------------------+
| | Unary plus and minus | ``+``, ``-`` |
+ +-------------------------------------+--------------------------------------------+
| | Logical NOT | ``!`` |
+ +-------------------------------------+--------------------------------------------+
| | Bitwise NOT | ``~`` |
+------------+-------------------------------------+--------------------------------------------+
| *3* | Exponentiation | ``**`` |
+------------+-------------------------------------+--------------------------------------------+
| *4* | Multiplication, division and modulo | ``*``, ``/``, ``%`` |
+------------+-------------------------------------+--------------------------------------------+
| *5* | Addition and subtraction | ``+``, ``-`` |
+------------+-------------------------------------+--------------------------------------------+
| *6* | Bitwise shift operators | ``<<``, ``>>``, ``>>>`` |
+------------+-------------------------------------+--------------------------------------------+
| *7* | Bitwise AND | ``&`` |
+------------+-------------------------------------+--------------------------------------------+
| *8* | Bitwise XOR | ``^`` |
+------------+-------------------------------------+--------------------------------------------+
| *9* | Bitwise OR | ``|`` |
+------------+-------------------------------------+--------------------------------------------+
| *10* | Inequality operators | ``<``, ``>``, ``<=``, ``>=`` |
+------------+-------------------------------------+--------------------------------------------+
| *11* | Equality operators | ``==``, ``!=`` |
+------------+-------------------------------------+--------------------------------------------+
| *12* | Logical AND | ``&&`` |
+------------+-------------------------------------+--------------------------------------------+
| *13* | Logical OR | ``||`` |
+------------+-------------------------------------+--------------------------------------------+
| *14* | Ternary operator | ``<conditional> ? <if-true> : <if-false>`` |
+------------+-------------------------------------+--------------------------------------------+
| *15* | Assignment operators | ``=``, ``|=``, ``^=``, ``&=``, ``<<=``, |
| | | ``/=``, ``%=`` |
+------------+-------------------------------------+--------------------------------------------+
| *16* | Comma operator | ``,`` |
