我如何为我从我的数组创建的<button>赋予它们自己的ids？

var myArray = ["按钮1", "按钮2", "按钮3"];
var buttonContainer = document.getElementById("button-container");

for (var i = 0; i < myArray.length; i++) {
  var button = document.createElement("button");
  var buttonId = "button-" + i; // 生成唯一id
  button.id = buttonId;
  button.innerHTML = myArray[i];
  buttonContainer.appendChild(button);
}
