=="Object" Syntax and Note==



<source lang="javascript">
Note:
This object provides the basic building blocks for creating customized objects.
To create a custom object, use the following steps:
1. Using the new keyword, instantiate the object into a variable.
var myObject = new Object();
2. Add each property to the object by choosing a property name and assigning a value to it.
myObject.firstName = "Joe"
3. Add each method to the object by choosing a method name and assigning a function to it.
myObject.age = function1;

Syntax:

var objectName = new Object()
objectName.memberName
