简单的Javascript OOP混淆[重复]

要在javascript中创建一个新的空对象，我们可以用2种方式编写。 1.使用对象文字语法：

const obj = {}

2.或使用构造函数的语法：

const obj = new Object()

Today I accidentally typed out const obj = new Object saw it also worked, where it should've thrown an error because I'd not invoked the constructor function which is done by a set of parenthesis.

I know that the new operator with a constructor function does 3 things.
1. creates a new empty object.
2. sets the value of this to the new object.
3. return the newly created object from the constructor function.

构造函数调用是可选的吗？ 那我想念什么呢？
