Having tried it, it's an "almost there" solution. Termux is a proot, not a chroot. This means you can't do certain things. You end up in a state where you can run nodejs and react, but you can't run create-react-app successfully. Rustup doesn't work in Termux, when it does booted into Linux on the same chromebook. You can git clone, but you can't clone a repo from a USB stick. Every single time I tried to do any development on it, the attempt ended in "nearly works" frustrations.
