Code.org is a non-profit organization and eponymous website led by Hadi Partovi that aims to encourage people, particularly school students in the United States, to learn computer science. The website includes free coding lessons and the initiative also targets schools in an attempt to encourage them to include more computer science classes in the curriculum. On December 9, 2013, they launched the Hour of Code 2013 nationwide to promote computer science during Computer Science Education Week until December 15, 2013.
