Things to clear up before jumping into the world of React

wtf-proto.md

1. Clearing the confusion between prototype, proto and [[Prototype]]

prototype

  function Dog(name) {
    this.name = name; 
    this.speak = function() {
        return this.name + " says woof";
    }
  }

  console.log(Dog.prototype);

  // The Output
  {
    constructor: Dog(name) {
      this.name = name;
      this.speak = function() {
          return this.name+" says woof";
      }
    },
    __proto__: Object { ... }
  }

I have found 2 blog posts that make the topic extremely clear.

Here are the 2 links:

1. __proto__ vs prototype

2. [[Prototype]]
