getAttribute
var element = document.getElementById("foo"); for (let i = 0; i < 1000; ++i) { var originalAttribute = element.getAttribute("data-foo"); element.setAttribute("data-foo", String(i)); var newAttribute = element.getAttribute("data-foo"); }
dataset
var element = document.getElementById("foo"); for (let i = 0; i < 1000; ++i) { var originalAttribute = element.dataset.foo; element.dataset.foo = String(i); var newAttribute = element.dataset.foo; }
