var e1 = document.createElement('div');
var e2 = document.createElement('div');
var e3 = document.createElement('div');
var e4 = document.createElement('div');
var es = [e1, e2, e3, e4];
Tests:

  • append()

     
    document.body.append(e1, e2, e3, e4);

  • appendChild()

     
    document.body.appendChild(e1);
    document.body.appendChild(e2);
    document.body.appendChild(e3);
    document.body.appendChild(e4);

  • append() with apply()

     
    document.body.append.apply(document.body, es);

  • appendChild() with loop

     
    for (var i = 0; i < es.length; i++) document.body.appendChild(es[i]);
