JavaScriptCore is the JavaScript engine used in WebKit. It consists of the following building blocks: lexer, parser, start-up interpreter (LLInt), baseline JIT, a low-latency optimizing JIT (DFG), and a high-throughput optimizing JIT (FTL).

This build comes from the GTK port of WebKit (API version 6.0).

This package contains the introspection data, which can be used by packages using the GIRepository format to generate dynamic bindings.
