whole time i was thinking there was something wrong with my code, why my own database is taking a whole 3seconds to complete the query, found out the s3 provider was taking the 3s, my code was just taking µs

My bytebeat was not working on the web because I was parsing the expression on every sample rate, like 8000 times per second, and it was slow for generating the value for audio buffers, which is why audio was cracking up, but running great in the desktop app
I actually used arena allocator properly

Parsers are recursive because languages are recursive. Lexers are not recursive.

lexer modes are useful, but they didn't teach me in the textbook!
Imagine you are making a programming language in which you want to support the feature of template strings, like this:
> console.log(`${1 + 2 * 3} equals 7`)
7 equals 7
