Why Local variable is preferred over Global variable ?
In my point of view Global variable has some advantage with Local variables is preferreddue to the following reasons:-
When we declare any global variable in web page then in case of error and logic its very
difficult to see on which line this variable is used and whats his value if we have more
than 2000 lines and all the functions in web page using that Global Variable so Global
variables can make the logic of a Web page difficult to understand.
As we know we can use Global variable everywhere so Global variables also make thereuse and maintenance of your code much more complex.

We can put Event handlers in the body of web page and also in attributes of HTML.
From the attribute we can call any JavaScript function that will do his operation andcome back. Now we can also interact with server side with the help of AJAX in
JavaScript function.
