通过key值动态引用对象属性会报错：
element implicitly has an 'any' type because expression of type 'string' can't be used to index type
解决方案：
const getKeyValue = <T extends object, U extends keyof T>(obj: T) => (key: U) => obj[key];

字典对象属性引用：

interface GenericDict<T> {
       [key: string]: T;
}

let dictionary: GenericDict<string[]> = {};
dictionary["example"] = ["foo"];
// Works fine!

方便点：
let dict:{[key:string]:string[]} = {};
