iSH is a Linux shell environment running locally on iOS device using a usermode x86 emulator. We can install Node.js with it.

Update on Sat, 27 Apr 24: It's okay for simple things since it runs emulated. Installing zsh with oh-my-zsh and when under a git directory, any command takes a while to execute as the shell shows the git branch and computing that is taking time. When I am in other directories that doesn't have git, its working fine.
