Any idea how I can view the implementation of native javascript methods specifically the sort method. The reason why I am looking for this I am just wondering what the algorithm used is and what is the complexity of the same.
I am sorting a huge json object in javascript and I was wondering if I should write my own mety hod for the same.
Also does the implementation differ from browser to browser?
Take a look at the WebKit implementation: https://gist.github.com/964673. Apparently, it uses min sort/selection sort. From: http://svn.webkit.org/repository/webkit/trunk/Source/JavaScriptCore/runtime/ArrayPrototype.cpp
SpiderMonkey seems to indeed use MergeSort. See: http://hg.mozilla.org/mozilla-central/file/28be8df0deb7/js/src/jsarray.cpp.
