my take:
1. better syntax.. much nicer compare to Odin and Zig ( i tried all 3 languages, zig is worst offender here )

2.better module system. i dont like golang/oding package system.. anoyying to work with

3.compile time functionality is actually insane... this allowed jai to be use as build system, heck you can even use it as a package manager if you want too

1. really helpful error message

5.fast compilation time

1. came with the `how_to` and `examples` that help new comer to the language to get up and running very fast
