javascript - If code is placed within an anonymous function, why can I access it from the console? -


i've noticed meteor's production ready code concatenated, minified, , wrapped in anonymous function.

in theory, should make meteor object , methods inaccessible through dom / window object / console.

why can still access objects placed within anonymous function through console?

javascript function scoped, means outer function variables accessible (and editable!) inner functions. goes way global (window) variables. example: 

(function() {   window.t ='foo'; })();

if run code in console, see t is, you'll see created/changed within function. meteor globally scopes few variables (meteor, check, etc.) can access them, in addition variables scope when create package. because each .js file anonymous function & if didn't export variables, you'd have write in 1 big file. exporting variables need, project stays modular. hope helps!
