What is the proper jargon to refer to a variable wrapped inside a function closure?
- by Rice Flour Cookies
In JavaScript, there is no such thing as a "private" variable. In order to achieve encapsulation and information hiding in JavaScript, I can wrap a variable inside a function closure, like so:
var counter = (function() {
var i = 0;
var fn = {};
fn.increment = function() { i++; };
fn.get = function() { return i; };
return fn;
{)();
counter.increment();
counter.increment();
alert(counter.get()); // alerts '2'
Since I don't call i a private variable in JavaScript, what do I call it?
