Before I was in the prototype chain of JavaScript, prototype inheritance and identifier lookup were somewhat confusing, For example, the following code: Copy Code code as follows: function Foo () {}; var foo = new Foo (); Foo.prototype.label = "Laruence"; alert (Foo.label); Output:laruence alert (Foo.label);//output:undefined Today we see the following figure: Javascrip
