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 3.0).

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