On the graceful writing of JavaScript

Here is a bit exaggerated, a little hanging, just casually say that they write a graceful way to JS.

Using jquery to develop, now very popular, greatly increased speed, but also can improve the quality of the code.

1, $.extend ()

// ...  --  indicates code    function  demo (opts)        {var defualtopts={...};        OPTs=$.extend ({},opts,defaults);        ...    }     /* use good $.extend () can be very good to pass parameters, look good beautiful */

2, {...}

/* {...} Using objects, this kind of object writing, code reusability is not strong can be used, because no need not to inherit,        but also can be very intuitive.     */    var demo={        init:function() {            this. Action ();            ...        },        action:function() {...},        render:function() { ...},        delegateevent:function() {...}    };

3, o.prototype={}

/* The object-oriented approach is very reusable and object-oriented is very principled, so the code looks good to understand */    function Demo () {        this. v= "...";           This . Init ();    }    Demo.prototype={        Constructor:demo,        init:function() {...},        ...    }

4, the writing of jquery plugin

/*closures-Preventing global pollution*/    (function($,w,undefined) {/*Prevent multiple loads*/        if(!$.fn.demo) {            /*extended jquery, can be $ (..). Demo () to execute*/$.fn.demo=(function(FN) {returnfn (); })(function(){                functionDemo () {Console.log (1); }                returndemo;        }); }}) (jquery,window,undefined);

Now is understood, as to what design pattern, this currently only know its type does not understand its specific use, this is the experience mode, need a lot of experience is experienced.
