javascript - Is jQuery an implementation of the Decorator Design Pattern? -

-

it decorates objects, think is, i'm not sure.

example

jquery(document).hide()

changes document object adding style.

edit:

if not decorator design pattern? it? there must pattern name it!

jquery best fits facade pattern, "define higher-level interface makes subsystem easier use." example, .css() , .hide() features designed ease of use, , jquery's ability perform action multiple elements @ once:

$('.foo').css({left: '100px', top: '100px'}).hide(); // jquery  // pure javascript for(var = document.getelementsbyclassname('foo'), = 0; < a.length; ++i) {     a[i].style.left = '100px';     a[i].style.top = '100px';     a[i].style.display = 'none'; }

jquery seems fit decorator pattern in such ways animation functionality. normal html dom elements not offer timed animations , attached queues, jquery adds that. in other areas, jquery provides same functionality available accessing underlying dom elements directly.

but there, doesn't fit, jquery not "dynamically keeping same interface."
