oop - JavaScript Prototype property stealing / inheritance -

is correct way prototype inheritance , property 'stealing??'/inheritance. want inherit properties person constructor + methods.

function product(name, price) {     this.name = name;     this.price = price; } product.prototype.tellme = function() {     console.log('name = ' + this.name + ', price = ' + this.price); }  function food(name, price, category) {     product.call(this, name, price);     this.category = category; } food.prototype = object.create(product.prototype); food.prototype.constructor = food;  var b = new food('name', 123, 'category'); console.log(b); b.tellme(); var = new product('name2', 321); console.log(a); 

i appreciate if give me example. thanks!

latest javascript standard, ecma6, enables perform inheritance writing class in similar fashion java oop. developer highly familiar java oop, have found approach easy understand , adapt. @ attached snippet code rewritten. hope helps.

'use strict';  class product{    constructor(name,price){      this.name = name;      this.price = price;    }        tellme(){        console.log('name = ' + this.name + ', price = ' + this.price);    }  }    class food extends product{    constructor(name, price, category){      super(name, price);      this.category = category;    }  }    var b = new food('name', 123, 'category');  console.log(b);  b.tellme();    var = new product('name2', 321);  console.log(a);
