   * Stops the code in <a href="#/p5/draw">draw()</a> from running repeatedly.
   *
   * By default, <a href="#/p5/draw">draw()</a> tries to run 60 times per
   * second. Calling `noLoop()` stops <a href="#/p5/draw">draw()</a> from
   * repeating. The draw loop can be restarted by calling
   * <a href="#/p5/loop">loop()</a>. <a href="#/p5/draw">draw()</a> can be run
   * once by calling <a href="#/p5/redraw">redraw()</a>.
   *
   * The <a href="#/p5/isLooping">isLooping()</a> function can be used to check
   * whether a sketch is looping, as in `isLooping() === true`.
   *
   * @method noLoop
   *
   * @example
   * function setup() {
   *   createCanvas(100, 100);
   *
   *   // Turn off the draw loop.
   *   noLoop();
   *
   *   describe('A white half-circle on the left edge of a gray square.');
   * }
   *
   * function draw() {
   *   background(200);
   *
   *   // Calculate the circle's x-coordinate.
   *   let x = frameCount;
   *
   *   // Draw the circle.
   *   // Normally, the circle would move from left to right.
   *   circle(x, 50, 20);
   * }
   *
   * @example
   * // Double-click to stop the draw loop.
   *
   * function setup() {
   *   createCanvas(100, 100);
   *
   *   // Slow the frame rate.
   *   frameRate(5);
   *
   *   describe('A white circle moves randomly on a gray background. It stops moving when the user double-clicks.');
   * }
   *
   * function draw() {
   *   background(200);
   *
   *   // Calculate the circle's coordinates.
   *   let x = random(0, 100);
   *   let y = random(0, 100);
   *
   *   // Draw the circle.
   *   // Normally, the circle would move from left to right.
   *   circle(x, y, 20);
