Oxygen

If we believe that oxygen is responsible for life in our body then we have to believe that oxygen is also responsible for decay of our body parts which results dead body.

How jQuery works?

We might have seen some activities in javaScript such as hiding an image, color change of text while hovering mouse, changing content periodically, get notification about new messages or tweets, getting  recent message or tweets on top and old getting below new post etc. All we can do it in JavaScript but we have to know some coding stuff and hence time consuming.

Suppose someone providing you service for all requirements for your each single javaScript stuff, it would be excellent in terms of time consuming, error free performance, efficiency etc.

jQuery provides us such services. It is just an add-on library to JavaScript. So it is easy to implement. We can see jQuery as written JavaScript code to implement directly. In general, jQuery does the coding stuff for us.
