<div>Po co ponowne wprowadzanie? Ponieważ {{Glossary("JavaScript")}} osławiony jest jako <a href="http://crockford.com/javascript/">najbardziej niezrozumiany język świata</a>. Często wyśmiewany jest jako bycie zabawką, jednak pod warstwą jego prosoty czekają potężne funkcje. Obecnie JavaScript używany jest w niewiarygodnie dużej ilości wysokoprofilowych aplikacji, pokazując, że dogłębne zrozumienie tej technologii jest ważną umiejętnością dla każdego, webowego jak i mobilnego, dewelopera.</div>
-<div></div>
+
<div>Warto rozpocząć od zaznajomienia się z historią tego języka. JavaScript został stworzony w 1995 roku przez Brendah Eich, który w tym czasie był inżynierem w Netscape. Pierwszy raz JavaScript został wydany z Netscape 2 początkiem 1996 roku. Pierwotnie miał on być nazywany LiveScript, został jednak przemianowany za sprawą feralnej decyzji marketingowej, która miała na celu wykorzystanie popularności języka Java Sun Microsystem - pomijając znikome części wspólne. Od tego czasu jest to źrodłem wielu nieporozumień.  </div>
-<div></div>
+
<div>Kilka miesięcy poźniej Microsoft wydał JScript razem z Internet Explorer 3. Był to w większości kompatybilny i podobny w pracy do JavaScript. Kilka miesięcy po tym, Netscape zgłosił JavaScript do <a href="http://www.ecma-international.org/">Ecma International</a>, europejskiego stowarzyszenia standaryzującego, czego rezultatem było wydanie pierwszej edycji {{Glossary("ECMAScript")}}. Standard otrzymał znaczącą aktualizację jako <a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm">ECMAScript edition 3</a> w 1999 roku i od tego czasu został prawie niezmieniony. Czwarta edycja została porzucona z powodu różnic politycznych dotyczących złożoności języka. Wiele części czwartej edycji uformowało podstawy dla piątej ECMAScript - opublikowanej w grudniu 2009 roku, oraz szóstej, której publikacja wypadła w czerwcu 2015 roku.</div>

<div class="note">
<p>Od tej pory określenie "JavaScript" będzie używane w odniesieniu do ECMAScript, ponieważ określenie to jest bardziej rozpoznawalne.</p>

Рекомендуется никогда не переопределять на стороне сервера явный выбор пользователем языка.
