Using TypeScript super()

Question

I am trying to extend a class in TypeScript. I keep receiving this error on compile: 'Supplied parameters do not match any signature of call target.' I have tried referencing the artist.name property in the super call as super(name) but is not working.

Any ideas and explanations you may have will be greatly appreciated. Thanks - Alex.

class Artist {   constructor(     public name: string,     public age: number,     public style: string,     public location: string   ){     console.log(`instantiated ${name}, whom is ${age} old, from ${location}, and heavily regarded in the ${style} community`);   } }  class StreetArtist extends Artist {   constructor(     public medium: string,     public famous: boolean,     public arrested: boolean,     public art: Artist   ){     super();     console.log(`instantiated ${this.name}. Are they famous? ${famous}. Are they locked up? ${arrested}`);   } }  interface Human {   name: string,   age: number }  function getArtist(artist: Human){   console.log(artist.name) }  let Banksy = new Artist(   "Banksy",    40,   "Politcal Graffitti",   "England / Wolrd" )  getArtist(Banksy);

The super call must supply all parameters for base class. The constructor is not inherited. Commented out artist because I guess it is not needed when doing like this.

class StreetArtist extends Artist {   constructor(     name: string,     age: number,     style: string,     location: string,     public medium: string,     public famous: boolean,     public arrested: boolean,     /*public art: Artist*/   ){     super(name, age, style, location);     console.log(`instantiated ${this.name}. Are they famous? ${famous}. Are they locked up? ${arrested}`);   } } 

Or if you intended the art parameter to populate base properties, but in that case I guess there isn't really a need for using public on art parameter as the properties would be inherited and it would only store duplicate data.

class StreetArtist extends Artist {   constructor(     public medium: string,     public famous: boolean,     public arrested: boolean,     /*public */art: Artist   ){     super(art.name, art.age, art.style, art.location);     console.log(`instantiated ${this.name}. Are they famous? ${famous}. Are they locked up? ${arrested}`);   } }
