JavaScript is a client-side scripting language used on webpages. It was originally developed by Brendan Eich of Netscape Communications Corporation. K-Meleon supports JavaScript versions up to the ECMAScript 6 standard. Websites that use ECMAScript 2021 features should fall back to a non-JavaScript version of the page on K-Meleon.

JavaScript is not related to the Java programming language.
