I found the examples quite straightforward . you take in 2+ objects and get back 1 merged object. (it does not seem to have anything to do with inheritance)

Hi Dormilich, I got some idea about jQuery.extends , thanks for your help , pls verify my idea as I know depicted below:
$.extend(target ,objects...) --->Extends the target
object with one or more specified objects.Returns the
original,unmodi fied object.

It's used mainly in creating plugins. For example,
in a plugin function there need some default
objects, some time we need to pass our own
preference(obje cts), in that time we need
to extend the deafault object with our own

eg:

(function($) {
  $.fn.say = function(options) {
    var ops = {
      'word' : 'Hello'
    };
    return this.each(function() {
      if (options) {
        // here I merge the users inputted 'options' object
        // with my 'ops' object.
        $.extend(ops, options);
      }
      $(this).html(ops.word);
    });
  };
})(jQuery);

and call this as :

$(document).ready(function() {
  $('div').say();
});

Would make all div's within a document contain the html 'Hello'.
Now, using $.extend() we can override the word hello with 'goodbye'.

$(document).ready(function() {
  $('div').say({word: 'Goodbye'});
});

Am I right Dormilich, If my understanding has any
problem advise me
