codon

Well, the truth is there's a lot more to JITing than what I wrote in the article, just because JITing didn't fit the vibe of the rest of the article that well. Anyway, yes theoretically you can. Recently folks creating Codon (https://github.com/exaloop/codon) did it for Python using a cool form of type inference. That said, I don't think any mainstream JS VMs do it. Most recent work I know in AOT compilation for JS seems to use some profile-guided optimization and not static type inference. For example, look at the architecture at 6:38 and also discussion about types here: https://youtu.be/pVhcyKf3efM?t=469). Something similar seems to be true for the project described here: https://www.youtube.com/watch?v=_T3s6-C38JI The story seems to be a bit different for hopc: https://www.youtube.com/watch?v=iY1EXHQ6IeQ The video starts by giving goo

I hope one day the compiler itself will be optimized even more: https://github.com/exaloop/codon/issues/137

Biggest problem at the moment is async support, I guess https://github.com/exaloop/codon/issues/71

The license is the "Business Source License 1.1" [1]. The Business Source License (BSL) 1.1 is a software license created by MariaDB Corporation. It's designed as a middle ground between fully open-source licenses and traditional proprietary software licenses. It's kind of neat because it's a parameteric license, in that you can change some parameters while leaving the text of the license unchanged. For codon, the "Change Date" is 2028-03-01 and the "Change License" is "Apache License, Version 2.0", meaning that the license will change to Apache2 in March of 2028. Until then, I guess you need to make a deal with Exaloop to use codon in production. [1] https://github.com/exaloop/codon?tab=License-1-ov-file#readm...

It may not be common, but I did find these (fairly popular projects) which don't appear to allow production usage: https://github.com/fingerprintjs/fingerprintjs/blob/master/L... https://github.com/exaloop/codon/blob/develop/LICENSE Here are some others: https://github.com/search?q=%22Business+Source+License%22+%2...
