 JavaScript wurde im Jahr 1995 von Brendan Eich bei Netscape entwickelt. Ursprünglich war es als einfachere Skriptsprache für Websites gedacht, ergänzend zu Java, das für komplexere Webanwendungen verwendet wird. Die enge Integration in Websites und der in Browser eingebaute Support der Sprache haben dafür gesorgt, dass JavaScript weit häufiger für Web-Frontends verwendet wird als Java.

Başlangıçta, daha karmaşık web uygulamaları için Java'nın kullanıldığı siteler için daha basit bir betik dili olarak tasarlandı, ancak Web sayfalarıyla sıkı entegrasyonu ve tarayıcılardaki yerleşik desteği nedeniyle Java'dan daha yaygın hale geldi.
