Noise vs Random

const WIDTH = Math.min(window.innerWidth, window.innerHeight, 480);

let xoff = 0;

function setup() {
  createCanvas(WIDTH, WIDTH);
}

function draw() {
  background(51);

  const x = map(noise(xoff), 0, 1, 0, width);
  xoff += 0.01;
  ellipse(x, height / 4, 24, 24);

  const xr = map(random(), 0, 1, 0, width);
  ellipse(xr, (height * 3) / 4, 4, 4);
}
