just VS shellb

just

https://github.com/just-js/just Is another for a V8 runtime, it really shows how well optimized it is. https://www.techempower.com/benchmarks/#section=data-r21

i just tried recompiling v0.0.2 (https://github.com/just-js/just/releases/tag/0.0.2) of just-js and comparing it to current. for the completely static build on ubuntu 22.04 i see following:

0.0.2 (v8 v8.4.371.18) - file size: 15.2 MB, startup RSS: 8.4 MB

Not at all. Javascript, as well as java compiled into the bytecode, but just incrementally and at the runtime. You cannot compile typescript into bytecode directly (at least it intend to be like that). You can even compile js to executable (https://github.com/just-js/just). So no, typescript transpiles to javascript, whereas scala compiles to bytecode, it's different things

Trust me, these guys are insane and go to really extreme levels and use optimization techniques which are not generally prevalent among the general programming fraternity. for eg, look at pico.v it is awesome and just-js is truly unbelievable, then there is faf, most of them combine low level programming trickery to reach those insane numbers. Also some of the code may not be useful in a production app but they actually extract the juice out of the metal at every instance. Memory optimizations, compiler optimizations, postgresql wire implmentations, rust black magic, these guys are really crazy and passionate.

Great question, initially I was aware of only plain old makefiles, this was back in 2010, then I came to know about autoconf which was a huge pain, then picked up cmake which was slightly better and stable, then I read about xmake, then meson, then scons and integrated all of them by hand, finally a couple of years ago, I was overwhelmed with the incremental changes to the framework causing build files to change and I was not able to keep up, so wanted something super easy and simple and hence create a simple stupid build tool called shellb. Then was reading about sandboxed builds and started working on bazel I had made a resolution to not write any more build files for any new tools, so integrated the generator within shellb, just last month heard about buck and then buck2 and incorporated buck2 generator within shellb too. So honestly if you ask me, as of today I know most of the tools inside out, and have auto-generated build files for bazel and buck2. Thanks for the interest and the lovely question.
