Better JavaScript — Prototypes

Write more robust constructors and get/set prototypes. In this article, we'll look at ways to improve our JavaScript code. Closures are Better than Strings for Encapsulating Code. We should never have ...

Like any kind of apps, JavaScript apps also have to be written well.

Otherwise, we run into all kinds of issues later on.

In this article, we’ll look at ways to improve our JavaScript code.

Object.getPrototypeOf or proto

Since ES6, __proto__ has become a standard property of an object.

We can get and set it like any other property.

For instance, we can write:

const obj = {};

console.log(obj.__proto__);

to get the prototype of obj .

We get the object’s prototype with the __proto__ property.

We can set it by writing:

const obj = {};
obj.__proto__ = {
  foo: 1
};
console.log(obj.__proto__);

and we get {foo: 1} as the prototype.

If we want to create an object with a prototype, we can also call Object.create with a prototype.

So we can write:

const obj = Object.create({
  foo: 1
})

and we get the same result.

We cal also use the Object.getPrototypeOf method to get the prototype of an object.

For instance, we can write:

Object.getPrototypeOf(obj)

and we get the same result as getting the __proto__ property.

The __proto__ property is standard, so we can safely use it to get and set the prototype.
