JavaScript Object.create() Method

The Object.create() method is used to create a new object with the specified prototype object and properties. We can create an object without a prototype by Object.creates (null).

Syntax:

Parameter

prototype: It is the prototype object from which a new object has to be created.

propertiesObject: It is an optional parameter. It specifies the enumerable properties to be added to the newly created object.

Return

Object.create() returns a new object with the specified prototype object and properties.

Browser Support:

Chrome	Yes
Edge	Yes
Firefox	Yes
Opera	Yes

Example 1

  const people = {    printIntroduction: function ()     {      console.log(`My name is ${this.name}. Am I human? ${this.isHuman}`);    }  };  const me = Object.create(people);  me.name = “Marry”; // “name” is a property set on “me”, but not on “person”  me.isHuman = true; // inherited properties can be overwritten  me.printIntroduction();  

Output:

"My name Marry. Am I human? true"

Example 2

  function fruits() {          this.name = ‘franco’;          }         function fun() {          fruits.call(this)   }            fun.prototype = Object.create(fruits.prototype);          const app = new fun();          console.log(app.name);  

Output:

"franco"

Example 3

  function fruits() {          this.name = ‘fruit’;          this.season = ‘Winter’;          }            function apple() {          fruits.call(this);          }            apple.prototype = Object.create(fruits.prototype);          const app = new apple();          console.log(app.name,app.season);          console.log(app.season);  

Output:

"fruit"   "Winter"  "Winter"
