# Curly braces

ActionScript event handlers, class definitions, and functions are grouped together into blocks with curly braces (`{})`, as in the following examples:

    // Event handler
    on(release) {
    	myDate = new Date();
    	currentMonth = myDate.getMonth();
    }

    // Class
    class Circle(radius) {
    }

    // Function
    circleArea = function(radius) {
    	return radius * radius * MATH.PI
    }
