[javascript] Javascript - Track mouse position

Here’s a combination of the two requirements: track the mouse position, every 100 milliseconds:

var period = 100,
    tracking;

window.addEventListener("mousemove", function(e) {
    if (!tracking) {
        return;
    }

    console.log("mouse location:", e.clientX, e.clientY)
    schedule();
});

schedule();

function schedule() {
    tracking = false;

    setTimeout(function() {
        tracking = true;
    }, period);
}

This tracks & acts on the mouse position, but only every period milliseconds.
