Hello, This is an exciting project. What is your roadmap and when can will release besen 2.0?

BeRo1985 commented 8 years ago

It'll be released when it's done, because the ECMAScript 2016 specification is considerably more complex and larger than the older ECMAScript 5.1 specification (where BESEN 1.x is based on).

The ECMAScript 2016 complaint parser and high-level AST-based optimizer of BESEN 2.x are already almost done, but the byte-code code generator including the whole execution virtual machine not yet, and that is also the exactly part, which is considerably more complex than at the older ECMAScript 5.1 specification, because ECMAScript 2016 has now generators (i.e. multiple coroutine-style execution contexts at the same time), symbols, classes, modules (i.e namespace-style constructs), proxies, TypedArrays, WeakMaps, etc.

Therefore BESEN 2.x will be released when it's done, but then it'll be a true major release, with new overall code design, new API, and better performance than with BESEN 1.x.
