If you ever wrote mildly substantial JavaScript, you noticed that that JavaScript is not as premiscuous as it may appear when it comes to namespaces.
If you define a variable outside any block of code, that variable is not necessarily available within the body of functions, say.
The solution is to use the a real global element and ‘attach’ it the global value as property. The object of choice is window and the solution is as simple as
window.myProperty="Yuval";
Thereafter the global value is accessible as
window.myProperty
Very elementary, but I always forget these facts…
