// 你的浏览器必须支持 for..of 循环
// 以及 for 循环中的 let 区域变量
for (let n of eArray) {
  console.log(n);
}

备选迭代

var arr = new Uint8Array([10, 20, 30, 40, 50]);
var eArr = arr.values();
console.log(eArr.next().value); // 10
console.log(eArr.next().value); // 20
console.log(eArr.next().value); // 30
console.log(eArr.next().value); // 40
console.log(eArr.next().value); // 50
