If you use "var" keyword you declare the variable as local, so when the execution exit from the function the variable can be destroyed by garbage collector. If you don't use "var" keyword the variable is stored in variables scope and can be destroyed only at the end of caller page execution. So the use of "var" keyword is very important.
