@laras126 There is error but at line 3 - insted "event" as an argument should be "e" (with "event" there is an error "e is not defined"), which is being passed further. In that case you don't have to declarate later "let" or "var".

window.onmousemove = logMouseMove;

function logMouseMove(e) {
	e = event || window.event;	
	mousePos = { x: e.clientX, y: e.clientY };
	console.log(mousePos);
}

Have a nice day! :)

That is so strange. When I execute window.event, it says undefined, however when I execute your code, everything work like charm.

@kingname, I think your error lies in executing regardless. His code is e = event || window.event so, even if the window.event is undefined, the code still works.
