ChaiScript VS V8

If you want to use C++ for scripting, take a look at Jason Turner's ChaiScript

3) Similiar to 2, but use more common scripting languages: chai, cs-script, sol2 (c++ framework to embed lua)

A few years back I actually went and made a ChaiScript based video game engine (https://16bpp.net/blog/post/masala-a-chaiscript-game-engine/). The end goal for it was to be able to make a Pacman like clone, but have all of the game logic implemented in ChaiScript. I actually found out as I added more realtime elements (implemented in ChaiScript) that it started to take much longer to process the game logic; the "game loop FPS" was under 60, which is not good. I actually proposition that ChaiScript move to a bytecode VM (https://github.com/ChaiScript/ChaiScript/issues/266), but I'm guessing that no movement was made on that front.

Maybe ChaiScript? It is not exactly what you are looking for, but very similar, in my opinion.

Behind the scenes: strtod, but I'm not gonna pretend I understand any of that ;)

Looks like these are the two commits, based on the issue number:

https://github.com/v8/v8/commit/0981e91a4f8692af337e2588562a...

https://github.com/v8/v8/commit/a2cae2180a7a6d64ccdede44d730...

Although there could be others.

Many of the languages with much faster implementations and quicker development have literal millions of dollars paying for their progress. I mean, look at the list of authors for V8. That's tens (if not hundreds) of billions of tech heavy weights contributing. Java was painfully slow for the longest time, even with all the money and promotion that Sun put behind it.

And also this nice article

https://v8.dev/blog/scanner

"The scanner chooses a specific scanner method or token based on a maximum lookahead of 4 characters, the longest ambiguous sequence of characters in JavaScript"

From what I understand, builtins are coded with v8 torque language in .tq files. However in src/builtins, there is no array-flat.tq file. Then where is it implemented?

It must be a fairly large echo chamber since it has room for Clang, GCC, V8, OpenJDK, Roslyn, etc. (The Zend parser for PHP seems to use some flavor of YACC, but given PHP, I don't know if that strengthens or weakens my point.)
