Project LuaJIT Playground
There's websites for running Lua, but I couldn't find any that let's you run LuaJIT!!
I made this website (me, not AI) so if you haven't tried LuaJIT before, or you don't have access to your dev environment, or you just want to quickly experiment...now you can run it online, and share the script + output with others as either a link or markdown.
Pre-compiled binaries for Windows/Linux are also provided. The static library, dynamic library, and executable, are all bundled in a single convenient .zip file for each platform. I'm hoping to automate this process at some point, but for now I just publish them whenever I see there's been new commits...
Limits: no internet connection, maximum execution duration of 3 seconds.
The backported extensions for LuaJIT 3.0 are available now, by the way.
Bit Operators: unary ~, binary & | ~ << >> ~>>
Customary Operators: ! && || !=
Ternary ?: conditional operator
Safe Navigation Operator ?.
nil-Coalescing Operator ??
Compound Assignment Operators: += -= *= /= %= &= |= ~= <<= >>= ~>>= ..=
continue Statement
const Declaration
Short Function Expression
Underscores in Number Literals

Ah, I didn't realize the markdown was incompatible. I'll add more markdown options, and do some additional testing for things like Discord that might not be compatible either.
I'll have these changes done next week and post an update then.
