The noCanvas() function in p5.js is used to remove the default canvas that is created by p5.js. This can be used for sketches that don’t require a canvas. It accepts no parameters.



Parameters: This function accepts no parameters.

The program below illustrates the noCanvas() function in p5.js:


function setup() {
  createCanvas(400, 300);
  // Create buttons for creating
  // and removing the canvas
  createBtn = createButton("Create Canvas");
  createBtn.position(30, 20);
  removeBtn = createButton("Remove Canvas");
  removeBtn.position(30, 50);
function removeDrawArea() {
  // Wrap noCanvas() in a try-catch
  // to prevent error in case there
  // exists no canvas to remove
  try {
  } catch (e) {
    print("No canvas found to remove");
function createDrawArea() {
  // Create a canvas with the
  // given dimensions
  createCanvas(400, 300);
function draw() {
  text("This is the canvas area", 50, 130);
  text("Canvas height: " + height, 50, 150);
  text("Canvas width: " + width, 50, 170);
