Difference between public, and having no access modifier on a TypeScript variable

  • 772

I have the following examples:

without public;

 export class Persona {
   name: string;
   lastName: string;
   dni: string;
}

With public;

 export class Persona {
   public name: string;
   public lastName: string;
   public dni: string;
}

If I leave the attribute without the access modifier, is it public by default? It may be something basic but I don't know what the correct definition would be (I want the attributes to be public to access them from the html in angular 5).

    In Typescript there are 3 access modifiers: public, private and protected ( See Reference for more details)

    • public: It is the default modifier . This is so because Javascript does not have these modifiers and everything is public, so for consistency it is normal for it to be the default value.

    • private: The elements (attributes and methods) are only visible inside the class.

    • protected: Elements are only visible within the class and in classes that directly inherit from it.

  2. According to the documentation , in the Public, private, and protected modifiers subheading :

    In TypeScript, each member is public by default.

    So there is no difference between the two.
