Today we are discussing about the data types and operators
Everything that javascript manipulates, it treats as and object a window or a button.
An object has properties. a window has size,position,status,etc
An object can be manipulated with methods that are associated with that object a resize a window with resize to (150,200)
Types of Objects
JavaScripts objectes
Objects that are part of javascript
examples.window document
Browser objects
objects that contain info not about the contentsof the display but the browseritself
Examples history, navigator.
User defined object
Object-Based, Not Object-Oriented
JavaScript is not a true object-oriented language like C++or Java
Itis so because it lacks two k ey features
A formal inheritance mechanism Strong typing
The Concept of objects and associated properties and methods is a very powerful idea, and we will be talking about it a lot during this course.
However today our focus will be on someof the nitty gritty details of javascript.
