Editing Esoteric programming language (section)

=== JSFuck ===
[[JSFuck]] is an esoteric programming style of [[JavaScript]], where code is written using only six characters: <code>[</code>, <code>]</code>, <code>(</code>, <code>)</code>, <code>!</code>, and <code>+</code>. 
Unlike Brainfuck, which requires its own compiler or interpreter, JSFuck is valid JavaScript code, meaning JSFuck programs can be run in any [[web browser]] or engine that interprets JavaScript.<ref>{{Cite web|url=https://thedailywtf.com/articles/bidding-on-security|title=Bidding on Security|last=Bailey|first=Jane|date=2016-02-29|website=The Daily WTF|language=en|access-date=2020-03-02}}</ref><ref>{{Cite web|url=https://alligator.io/js/exploring-jsfck/|title=Exploring JSF*ck|website=alligator.io|language=en|access-date=2020-03-02|archive-url=https://web.archive.org/web/20200302154212/https://alligator.io/js/exploring-jsfck/|archive-date=2020-03-02|url-status=dead}}</ref> It has been used in a number of [[cross-site scripting]] (XSS) attacks on websites such as [[eBay]] due to its ability to evade cross-site scripting detection filters.<ref name="ArsTechnica 2016 eBay">{{cite web|url=https://arstechnica.com/security/2016/02/ebay-has-no-plans-to-fix-severe-bug-that-allows-malware-distribution/|title=eBay has no plans to fix "severe" bug that allows malware distribution [Updated]|work=Ars Technica|author=Dan Goodin|date=3 February 2016}}</ref>
