i once heard that optimizing compilers are designed to make shit code fast and that has changed me forever
Ayou heard it here, folks
write shit code cause the compiler can make it fast!!!!!!!!!!!!111111111111111

Mif ever you find yourself prematurely optimizing code, just remember: someone got paid a lot of money so you don't have to do this
Lthe compiler cant optimize my code if i disable the optimization flags
Li always win

Mv8 has a special case if you try to use a javascript object as a class with a fixed size structure, or as a hashtable with thousands of members. both of them perform reasonably well
Mall objects in js are technically reference types, including numbers
Ah u h ?
Mjs is really weird
Ajs gets curseder by the day
Mtechnically this is also true of lua but more directly in lua as you can actually modify the metatable of such types
Pmy favourite part was where v8 said "it's v8ing time" and proceeded to v8 all over the place
Ljs is like if a language designed for tiny scripting was made into a langauge people try to push for desktop apps and server backends
Loh wait
Aim entirely convinced that js was designed by a monkey on drugs and the result was then accepted for some reason
Meich said he created javascript so that we wouldn't end up with PHP on the frontend
Msince that's where netscape was heading
Land now we have javascript on the backend
Lits horrible
Lwhy must god curse us like this
Aphp in the front end would not solve the problems
but it would help fix them
but it would help fix them
Mon the bright side, at least js has unicode!
Aw o w !
Mphp strings are just data
Lユニコード
Athat-
what-
uhm-
i mean
yes?
but
the number 1 is also data

Mnonononono
Lthey are just data
Mphp strings are just byte arrays
Mand php builtin functions have no notion of encoding
Athat is the case in most languages
Aah
Awell
Aphp is just built different
Lat least with a language like zig which does that, the whole stdlib specifies and only accepts UTF-8 aside from windows functions which need UTF-16 (which isnt stored as byte arrays anyway, so its clearly incompatible)
Mif you do indexOf('ッ') you get a different result depending on the encoding of the source code and the encoding of the string when it was read
Law man i love shift-jis
LGREAT invention
Ltotally hasnt haunted me for years
Mit could be
\xE3 \x83 \x83
\x30 \xC3
or whatever it is in shift-jis
\xE3 \x83 \x83
\x30 \xC3
or whatever it is in shift-jis
Lzig's solution to the problem is: if your source code is not UTF-8 its a compile error
Aas it should
Mgood
Lyup
Aoh yeah
Aside note
Areally annoying thing in rust
Ayou can't index strings
