var car='honda';. Here car is a variable holding a value “honda”.
Similarly an object i s also a variable, but an object can hold many values. For example var car = {type:"honda", model:"500", color:"white"};

The name:values pairs (in JavaScript objects) are called properties.
For example var car = {type:"honda", model:"500", color:"white"};
Here object car have properties:

  • type
  • model

Methods are actions that can be performed on objects.

Object Declaration

Object properties are accessed in two ways:
