如何修复 属性 的隐式数组访问

How to FIX implicit any of array access of property

我有这个代码:

function getKey(): string {
    return 'foo';
}

function dummy(): void {
    const object = {};
    const key: string = getKey();
    const value: any = 42;

    object[key] = value; // ERROR: TS7053: Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '{}'.
}

我知道错误存在是因为我启用了 noImplicitAny 以获得更清晰的代码,但是设置此 属性 的简洁方法是怎样的?

您可以声明一个 Record 类型:

function getKey(): string {
    return 'foo';
}

function dummy(): void {
    const object: Record<string, any> = {}; // Here you can define the type of value, example string or number.
    const key: string = getKey();
    const value: any = 42;

    object[key] = value; // Not error
}
