simple-vm's Issues

This code is just flat out bad.

Most of the code is redundant and bad, switch cases for instructions / mnemonics is fine but there's a way better way of doing this, it's called indirect threading and it's a popular for efficiency where you use goto statements and functions for specific mnemonics. Also it's not even turing complete, you're not even allowing for access of conditional branching, this is not going to be used for any programming language you think it would, this isn't a "simple VM", it's a bad VM. (Side note, your nop doesn't work, it just breaks out of the loop, no incrementation of the program counter, this is not simply doing "nothing", it's exiting the execution loop.
