javascript - 如何将新值推送到 JavaScript 对象数组

Question

我有一个具有包含数组的属性的对象，我想知道插入该数组的最佳方法是什么，这是对象：

const object1 = 
  {"users": [{"username":"john","email":"[e-mail]","id":"john_2011221"}, 
  {"username":"steve","email":"[e-mail]","id":"steve_201193841"}]};

我想做这样的对象：

const object1 = 
      {"users": [{"username":"john","email":"[e-mail]","id":"john_2011221"}, 
      {"username":"steve","email":"[e-mail]","id":"steve_201193841"}
      {"username":"Emily","email":"[e-mail]","id":"emily_20119567"}]};

使用Array#push.

object1.users.push({"username":"Emily","email":"[e-mail]","id":"emily_20119567"});
