any

TypeScript 也有一个特殊的类型，any，当你不希望某个特定的值导致类型检查错误时，你可以使用它。

TypeScript also has a special type, any, that you can use whenever you don't want a particular value to cause typechecking errors.

当一个值的类型为 any 时，您可以访问它的任何属性（这又将是 any 类型），像函数一样调用它，将它分配给（或从）任何类型的值，或者几乎任何其他东西这在语法上是合法的：

When a value is of type any, you can access any properties of it (which will in turn be of type any), call it like a function, assign it to (or from) a value of any type, or pretty much anything else that's syntactically legal:

let obj: any = { x: 0 };
// None of the following lines of code will throw compiler errors.
// Using `any` disables all further type checking, and it is assumed 
// you know the environment better than TypeScript.
obj.foo();
obj();
obj.bar = 100;
obj = "hello";
const n: number = obj;

当你不想写出一个长类型来让 TypeScript 相信特定的代码行是可以的时，any 类型很有用。

The any type is useful when you don't want to write out a long type just to convince TypeScript that a particular line of code is okay.
