The Wolfram Compiler is a long-term development project to enhance the Wolfram Language. An initial version is included in Version 12. The Wolfram Compiler translates an increasing portion of the Wolfram Language into optimized native machine code. This can be directly executed, converted into objects files of various formats or stored in dynamic libraries for subsequent use. Built on top of the latest modern compiler knowledge, it facilitates Wolfram Language access to a wide range of modern computer technologies.
