I was recently comparing the current version of json2.js with the version I had in my project and noticed a difference in how the function expression was created and self executed.
The code used to wrap an anonymous function in parenthesis and then execute it,
(function () {
// code here
})();
but now it wraps the auto-executed function in parenthesis.
(function () {
// code here
}());
There is a comment by CMS in the accepted answer of Explain JavaScript’s encapsulated anonymous function syntax that “both: (function(){})(); and (function(){}()); are valid.”
I was wondering what the difference is? Does the former take up memory by leaving around a global, anonymous function? Where should the parenthesis be located?
