Nah, just get butterflies

An assembler doesn't have any of the interesting parts of a compiler.

Anyway, the problem with Typescript is that it tends to obscure what's going on one layer below it in ways that don't happen in traditional compiled languages. We've had decades of development on tools that can work together with traditional compilers. Javascript has not, and there are frequent problems getting different tools at different layers of abstraction to march the same direction.

You can write asm in hex too https://grantmestrength.github.io/RetroComputerInstructionManual/intel8080.html just instead of instruction, write opcode https://dercuano.github.io/notes/8080-opcode-map.html#addtoc_2 https://www.pastraiser.com/cpu/i8080/i8080_opcodes.html https://en.m.wikipedia.org/wiki/X86_instruction_listings
