{{quote box|width = 200px|Anyway I know only one [[programming language]] worse than [[C (programming language)|C]] and that is Javascript. [...] I was convinced that we needed to build-in a programming language, but the developers, [[Tim Berners-Lee|Tim]] first, were very much opposed. It had to remain completely declarative. Maybe, but the net result is that the programming-vacuum filled itself with the most horrible [[Kludge|kluge]] in the history of computing: Javascript.|[[Robert Cailliau]]<ref>[[wikinews:Wikinews:Story preparation/Interview with Robert Cailliau]]</ref>}}

JavaScript was originally developed by [[Brendan Eich]] of Netscape under the name ''Mocha'', which was later renamed to ''LiveScript'', and finally to JavaScript mainly because it was more influenced by the [[Java programming language]].<ref>{{cite web|last=Krill |first=Paul |url=http://www.infoworld.com/article/08/06/23/eich-javascript-interview_1.html |title=JavaScript creator ponders past, future |publisher=InfoWorld |date=2008-06-23 |accessdate=2009-05-19}}</ref><ref name="computerworld">{{cite web|last=Hamilton|first=Naomi|url=http://www.computerworld.com.au/article/255293/-z_programming_languages_javascript|title=The A-Z of Programming Languages: JavaScript|publisher=computerworld.com.au|date=2008-06-31}}</ref>

LiveScript was the official name for the language when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995, but it was renamed JavaScript in a joint announcement with Sun Microsystems on December 4, 1995,<ref>[http://web.archive.org/web/20070916144913/http://wp.netscape.com/newsref/pr/newsrelease67.html Press release announcing JavaScript], "Netscape and Sun announce Javascript(TM)", PR Newswire, Dec 4, 1995</ref> when it was deployed in the Netscape browser version 2.0B3.<ref name="techvision">{{cite web |archiveurl=http://web.archive.org/web/20080208124612/http://wp.netscape.com/comprod/columns/techvision/innovators_be.html |archivedate=2008-02-08 |title=TechVision: Innovators of the Net: Brendan Eich and JavaScript |publisher=Web.archive.org |date= |accessdate=2010-06-14}}</ref>
