View Full Version : Any Apparent Dangers in Declaring Multiple Variables Globally?

12 Jul 2011, 6:26 PM
Hi All,

I made a similar post in the ExtJS2.2 sub-forum but I would like to hear the various opinions on Extjs 3.x specifically. So here it goes:

I am thinking of implementing all variables as "global variables" so that instead of initializing local variables in a return function and failing to destroy them, the code would call a function to destroy the global variable upon a completion action, like closing a window.

The actual question is:

Any issues or problems or things to take note if I were to switch to an ALL global variable approach?

Memory issues, security, and the worst one.. you'll have keep track of the variable names that you use..

Awful idea, please read Douglas Crockford's excellent book "Javascript: The Good Parts" so you never think to do this again.

Double posting is not a good thing to do either. I have deleted your post on the same matter from the GXT forum
