typescript is 类型保护

function isString(test: any): test is string{
    return typeof test === "string";
}

function example(foo: any){
    if(isString(foo)){
        console.log("it is a string" + foo);
        console.log(foo.length); // string function
 // 如下代码编译时会出错，运行时也会出错，因为 foo 是 string 不存在toExponential方法

	// 在 swagger 中定义 response 需要新建一个 class。但是从数据库里面查询出来的数据有些不需要返回。所以可以通过`class-transform` 进行清除


	// response class

	import { ApiProperty } from '@nestjs/swagger';
	import { Exclude, Expose, Transform } from 'class-transformer';

	@Exclude()
