@section Main Features
@item Small and easily embeddable: just a few C files, no external dependency, 210 KiB of x86 code for a simple ``hello world'' program.
-@item Fast interpreter with very low startup time: runs the 77000 tests of the ECMAScript Test Suite@footnote{@url{https://github.com/tc39/test262}} in less than 2 minutes on a single core of a desktop PC. The complete life cycle of a runtime instance completes in less than 300 microseconds.
