Javascript - Track mouse position

Question

I am hoping to track the position of the mouse cursor, periodically every t mseconds. So essentially, when a page loads - this tracker should start and for (say) every 100 m

Answer 1

onmousemove = function(e){console.log("mouse location:", e.clientX, e.clientY)}

Open your console (Ctrl+Shift+J), copy-paste the code above and move your mouse on browser window.
