javascript window.moveBy() move the window diagonally

Question

I’m starting to play around with Electron and javascript and I’m trying to make a window become wider over time, so I try to loop the window.resizeTo(tamanho da janela + 1,0) but the window widened only to the right so I tried to use the window.moveBy(-1,0) however the window always moves diagonally for more than I put 0 in y and always moves to the same direction even with the values being below 0

the only page code

    var wide = 128
    var FRAME = 200 ;
var loop = function() {
        window.resizeTo(wide,256);
        wide++;
        window.moveBy(01,0)
        setTimeout(loop, FRAME);
};
setTimeout(loop, FRAME);
