Boolean object in JavaScript attribute resolution _ Basics

Constructor property

Instance
Returns the function created by the prototype of the MyVar object:

var myvar = new Boolean (1);
Myvar.constructor;

Result output:

function Boolean () {[native code]}

Definitions and usage
The constructor property returns a reference to the Boolean function that created this object.

prototype Builder
Create a new method for the Boolean object:

Boolean.prototype.mycolor=function ()
{
if (this.valueof () ==true)
 {
 this.color= "green";
 }
else
 {
 this.color= "red";
 }
}

Create a Boolean object and add the MyColor method:

var a=new Boolean (1);
A.mycolor ();
var B=a.color;

b Result output:

Green

Definitions and usage
The prototype property gives you the ability to add properties and methods to an object.
When constructing a prototype, all Boolean objects add properties or methods by default.
Note: Prototype is a global property, which is for almost all JavaScript objects.
