Title
Body
I was reading on javascript garden http://bonsaiden.github.com/JavaScript-Garden/ about prototype in javascript and one of its example goes like this: function Foo() { this.value = 42; } Foo.prototype = { method: function() {} }; function Bar() {} // Set Bar's prototype to a new instance of Foo Bar.prototype = new Foo(); Bar.prototype.foo = 'Hello World'; // Make sure to list Bar as the actual constructor <------------------- Bar.prototype.constructor = Bar; Notice the line that reads Make sure to list Bar as the actual constructor. I really am lost about what this does/is. I have tried making new instances of Bar() with and without the last line. But call "value" or "method" on those instances return the exact same things. So I wonder, what's the need (I assume there must be one) of specifying the constructor? Thank You!!!
