JavaScriptの継承(伝統版)の書き方

Inko = function (name) {
  this.namae = name;
};

Inko.prototype.chirp = function () {
  console.log(this.namae);
};

Zuaka = function (name) {
  this.namae = name;
};

Zuaka.prototype = new Inko();
Zuaka.prototype.aka = function () {
  console.log("deko");
};

var souchan = new Zuaka("sou");
souchan.chirp();
souchan.aka();

var kaechan = new Inko("kae");
kaechan.chirp();

9～16行目Zuakaたこやき型の定義

Zuakaたこやき型にInkoたこやき型の定義をprototypeで継承

Inko = function (undefind) {
  this.namae = undefind; 
};

Inko.prototype.chirp = function () {
  console.log(this.namae);
};

souchan.chirp();
