Wikipedia excerpt: The code that would become WebKit began in 1998 as the KDE HTML (KHTML) layout engine and KDE JavaScript (KJS) engine. The WebKit project was started within Apple by Don Melton on June 25, 2001,[16] as a fork of KHTML and KJS. Melton explained in an e-mail to KDE developers[1] that KHTML and KJS allowed easier development than other available technologies by virtue of being small (fewer than 140,000 lines of code), cleanly designed and standards-compliant. KHTML and KJS was ported to macOS with the help of an adapter library and renamed WebCore and JavaScriptCore.[1] JavaScriptCore was announced in an e-mail to a KDE mailing list in June 2002, alongside the first release of Apple's changes.[17]
