javascript - ES6在类内部进行销毁(ES6 Destructuring with this inside a class)

Question

I have a function that returns a tuple [number, number, number] .

(我有一个返回元组[number, number, number]的函数。)

I want to use destructuring to assign to my class variables the values returned by the tuple like this:

(我想使用解构将元组返回的值分配给我的类变量，如下所示：)

let [this.a, this.b, this.c] = functionThatReturnsTupleWithThreeNumbers()

but this doesn't work.

(但这行不通。)

Answer 1

Just remove the let and you're good to go:

(只需删除let ，您就可以开始了：)

 class Foo { a; b; c; bar() { [this.a, this.b, this.c] = [1, 2, 3]; } } const foo = new Foo(); foo.bar(); console.log(foo);
