All cars have these properties, but the properties of each car are different.

All cars have these methods, but they are carried out at different times.

JavaScript object

In JavaScript, almost everything is an object.

In JavaScript, objects are very important, and when you understand objects, you can understand JavaScript.

You have learned the assignment of JavaScript variables.

The following code sets the value to "Fiat" for the variable car:

Varcar= "Fiat"

An object is also a variable, but an object can contain multiple values (multiple variables), each of which is rendered as a name:value pair.

Varcar= {name: "Fiat", model:500,color: "white"}

In the above example, three values ("Fiat", 500, "white") are assigned to the variable car.

The JavaScript object is a container for variables.
