类静态属性

Question

In the new ES6 Class syntax it is not possible to do

class Person {
    this.type = 'person';

But if I define the property inside the contructor it works :

class Person {
    constructor(name) { //class constructor
        this.name = name;
        this.type = 'person';
    }

I know the possibility to have properties outside methods is being discussed but as of today and what relates to the ES6 specs it is not possible.

Is my solution a correct way to define static properties for the Class (for semantic reasons I defined those properties inside the constructor but it seems to work inside other methods)? Is there a better way?

I was looking at the spec in Method Defenition and found no information about this.

Answer 1

You can create static getter:

 "use strict"; class Person { static get type() { return 'person' } } console.log(Person.type) // 'person' 

Answer 2

As already said, what you are doing is creating an instance property. Adding such properties in the constructor is what the constructor is there for. This hasn't changed with ES6.
