The subtraction assignment (-=) operator performs subtraction on the two operands and assigns the result to the left operand.

The throw statement throws a user-defined exception. Execution of the current function will stop (the statements after throw won't be executed), and control will be passed to the first catch block in the call stack. If no catch block exists among caller functions, the program will terminate.

The patternContentUnits attribute indicates which coordinate system to use for the contents of the <pattern> element.

The stroke-dasharray attribute is a presentation attribute defining the pattern of dashes and gaps used to paint the outline of the shape.
