Ultimate-Linux: Userspace for Linux in Pure JavaScript (github.com)

It’s never early to prepare for JavaScript complete takeover.

Very cool. Good use of quickjs, although it would have been cool if it somehow didn’t need a libc and just used the syscall interface. Makes me want to give that a try.

Reading the code, I was surprised to see that cd was implemented by calling out to the os library. I assumed that was something the shell or at least userspace handled. At what level does the concept of a “current directory” exist?

Kernighan and Ritchie wept. (Tears of joy at an awesome hack, or tears of sadness at an awesome hack?)

A very timely endeavor indeed https://devblogs.microsoft.com/typescript/typescript-native-...

I did something similar with TCL, the basis was using an extension I wrote to handle the UNIX stuff [0]. It operated an On-Premises cloud environment appliance, and `init` was just a TCL script (at one point it was a statically linked binary with the init script embedded, but that turned out to be overkill)

urgh

strange motivation and implementation. I mean it real. There are many existing open source projects that run Linux on JS.

Many comments here seem to miss the point: this is not running the Linux Kernel in JavaScript

This is the Linux Userland reimplemented in JavaScript

I am working something similar in Go, and writing an educative blog post series about it: https://serversfor.dev/linux-inside-out/

I remember some core Unix utilities reimplemented in Perl, mainly done for Win32 systems back in the day. OFC the performance coudn't compete with the ones written in C, but it was good enough.
