How many ways to create Objects in JavaScript

 We can 5 ways to create objects in JavaScript.

Lets understand how to Create it...

Demo URL



'use strict';
Example 1

var fruit = {};
fruit.name = 'Mango';
fruit.color = 'Yellow';
console.log(`fruit name ${fruit.name} and color is ${fruit.color}`);

Example 2

var fruit2 = { name: 'Mango'color: 'Yellow' };
console.log(`fruit name ${fruit2.name} and color is ${fruit2.color}`);

function Fruit(namecolor) {
  (this.name = name), (this.color = color);
}

Example 3

var fruit3 = new Fruit('Mango''Yellow');

Example 4

var fruit4 = new Fruit('Donut''Sprinkled Yellow');

console.log(`fruit name ${fruit3.name} and color is ${fruit3.color}`);
console.log(`fruit name ${fruit4.name} and color is ${fruit4.color}`);

console.log(`Check fruit3 proto ${Fruit.prototype === fruit3.__proto__}`);

// console.log(`Property descriptor
// ${JSON.stringify(Object.getOwnPropertyDescriptor(fruit,'name'))}`)

Example 5

var fruit5 = Object.create(Object.prototype, {
  name: {
    value: 'Mango',
    enumerable: true,
    writable: true,
    configurable: true,
  },

  color: {
    value: 'Yellow',
    enumerable: true,
    writable: true,
    configurable: true,
  },
});

console.log(`fruit name ${fruit5.name} and color is ${fruit5.color}`);
console.log(`Check fruit3 proto ${fruit.prototype === fruit5.__proto__}`);

var fruit6 = Object.create(Object.prototype, {
  name: {
    value: 'Mango',
    enumerable: true,
    writable: true,
    configurable: true,
  },

  color: {
    value: 'Yellow',
    enumerable: true,
    writable: false,
    configurable: true,
  },
});

fruit6.name = 'Sausages';
//compile error comment it later
//fruit6.color="Red";

for (var props in fruit6) {
  console.log(`${props} : ${fruit6.color}`);
}

console.log(
  `Fruit name ${fruit6.name} and color is ${
    fruit6.color
  } and proto ${JSON.stringify(fruit6.__proto__)}`
);

//Getter Setter

var fruit7 = {
  color: 'Yellow',
  get fruitcolor() {
    return this.color;
  },
  set fruitcolor(val) {
    this.color = val;
  },
};

console.log(`Fruit default color is ${fruit7.fruitcolor}`);

fruit7.fruitcolor = 'Yellow';

console.log(`Fruit changed color is ${fruit7.fruitcolor}`);

console.log(`Check Fruit3 proto ${Fruit.prototype === fruit3.__proto__}`);
