1	New expression	new <typename>
1	Array subscripting	<array>[<index>]
1	Member access	<object>.<member>
1	Function-like call	<func>(<args...>)
1	Parentheses	(<statement>)
2	Prefix increment and decrement	++, --
2	Unary plus and minus	+, -
2	Unary operations	delete
2	Logical NOT	!
2	Bitwise NOT	~
3	Exponentiation	**
4	Multiplication, division and modulo	*, /, %
5	Addition and subtraction	+, -
6	Bitwise shift operators	<<, >>
