Continuously executes the lines of code contained inside its block until the program is stopped or <b>noLoop()</b> is called. Calling <b>redraw()</b> will cause the code inside <b>draw()</b> to execute once and calling <b>loop()</b> will cause the code inside <b>draw()</b> to execute continuously. The <b>draw()</b> function is used in conjunction with <b>setup()</b>. The number of times <b>draw()</b> executes in each second may be controlled with the <b>delay()</b> and <b>framerate()</b> functions.
