Grouping Operator

Aside from being used in function calls, parentheses ( ) can also be used to group a phrase of code to override the precedence of various operators. Parentheses are also required in some statements, most notably if statements. Parentheses take the general form:

(expression)

The expression within the parentheses is evaluated and returned. Here are some examples:

if (x == y) {
 // Syntactically required for if statement trace("x and y are equal"); // Required for the function call
}
(5 + 6) * 7 // Force a nonstandard order of operation (x >= 100) || (y <= 50) // Parentheses not required but added for legibility x >= 100 || y <= 50 // No parentheses...a little harder to read
