// A short snippet for detecting versions of IE in JavaScript | |
// without resorting to user-agent sniffing | |
// ---------------------------------------------------------- | |
// If you're not in IE (or IE version is less than 5) then: | |
// ie === undefined | |
// If you're in IE (>=5) then you can determine which version: | |
// ie === 7; // IE7 | |
// Thus, to detect IE: | |
// if (ie) {} |

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.
Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:
function Foo(who) { | |
this.me = who; | |
} | |
Foo.prototype.identify = function() { | |
return "I am " + this.me; | |
}; | |
function Bar(who) { | |
Foo.call(this,"Bar:" + who); |
