| Now if we want to create other users, we can call `new User("Ann")`, `new User("Alice")` and so on. Much shorter than using literals every time, and also easy to read. | |||

| Let's note once again -- technically, any function can be used as a constructor. That is: any function can be run with `new`, and it will execute the algorithm above. The "capital letter first" is a common agreement, to make it clear that a function is to be run with `new`. | ||
| 让我们再次注意 -- 从技术上讲，任何函数都可以用作构造函数。即：任何函数都可以运行 `new`，它会执行上面的算法。 “首字母大写”是一个共同的约定，以明确表示一个函数将被运行 `new`， |

| Of course, we can add to `this` not only properties, but methods as well. | ||
| 当然，我们不仅可以将 this 添加到属性中，而且还添加到方法中。 |

| We can use constructor functions to make multiple similar objects. | ||
| - 构造函数只能使用 `new` 来调用。这样的调用意味着在开始时创建空的 `this`，并在最后返回填充的。 |

| In this chapter we only cover the basics about objects and constructors. They are essential for learning more about data types and functions in the next chapters. | ||
| 在本章中，我们只介绍关于对象和构造函数的基础知识。它们对于在下一章中更多地了解数据类型和功能非常重要。 |
