Typescript namespace

The role of namespace is mainly to prevent methods or functions with the same name The main thing is to do more
我们先来看一段代码

namespace padd {
    
  export class dog {
    
    name:String;
    constructor(name:String){
    
      this.name = name;
    }
    signUp(){
    
      console.log(`我的名字叫${
      this.name}`)
    }
  }

}
namespace bfsl {
    
  export class dog {
    
    name:String;
    constructor(name:String){
    
      this.name = name;
    }
    signUp(){
    
      console.log(`请叫我${
      this.name}`)
    }
  }
}

Here we define two namespaces padd 和 bfsl Below them all have a calldog的类 And that doesn't conflict or overwrite because they are in different namespaces

Now we use namespaces to instantiate these two classes Then call one of themsignUp方法

var paddDog = new padd.dog("狗狗");
var bfslDog = new bfsl.dog("大黄");

这里可以看到 我们 The way to take out the namespace is very simple 命名空间名.类名

Then we call the methods on it with the strength objectsignUp

paddDog.signUp();
bfslDog.signUp();

运行结果如下

没有任何问题
The following operations are all in the same file if not in the same file need to use import and export 调用方法 仍是 命名空间.类名
