JS: Object | JavaScript

JavaScript Object

Declaring JavaScript object instance, new keyword usage and the Object static class. ES6 and ES7 new functions/methods for object instance operations e.g. keys, values, entries etc.

An object is the instance of a class created in memory.

JavaScript objects are reference type.

How to create Objects in JavaScript

An object can be created with new keyword.

class Car{ } var c1 = new Car();

In the code above, the c1 is the instance of the classCar

Similarly we may define multiple instance of the same class, as many as we need.

var c1 = new Car(); var c2 = new Car(); var c3 = new Car();
JavaScript objects are reference through this keyword within class.
