How do I get what kind of device who visits my website? [duplicate]

Question

I am making a JavaScript game but I want the canvas to be different sizes depending if it is for instance an iPhone who visits

const canvas = document.querySelector("canvas"); canvas.width = 500;

So my question is how do I get the device information?

Answer 1

You can simply use the width and height property of the window.screen object

const width = screen.width;

const height = screen.height;
