javascript - 如何克服 typescript 的传播运算符限制？

Question

我试过声明无济于事。这是我想做的简单事情:

this.scoreStack = [...Array(3).keys()];

显然，typescript 不支持这种解构。 我收到:

Symbol "keys" cannot be properly resolved, probably it is located in an inaccessible module

有没有一种方法可以定义 keys() 方法并克服这个限制？

Answer 1

Is there a way that I can define the keys() method and get over this limitation

你可以很容易地声明它:

declare global {
    interface Array<T> {
        keys():string[];
    }
}

const x = [...Array(3).keys()];
