Window-reflecting body element event handlers：

if you assign one of the following event handlers on document.body, it will be reflected on window too, and vice versa.

• onblur, onerror, onfocus, onload, onresize, onscroll

const body = document.body;
body.onblur = function f(){};        // assigned on body
window.onblur                        // f: reflected on window

window.onresize = function g(){};    // assigned on window
body.onresize                        // g: reflected on body
