In which language is Chromium OS written?

I wonder in which language Chromium OS is written.I guess they have used C/C++ but did they put something different (Go)?

Did they used Assembly for low level code as I know that they had to change some things to make booting a lot faster?

ChromiumOS is based on Gentoo and uses a wide variety of languages to build; the vast majority are:

at runtime, ChromiumOS uses Rust/C++/C/Assembly the vast majority of the time, and once the browser is up, anything Chrome itself supports (so JavaScript is used a lot). there is some shell code with low level system boot up/maintenance, but there is no Go or Python or any other interpreted language on the system.

NB: i include awk and sed and similar languages under the "shell" umbrella which i think suffices for most people who are interested in this question.

Asking what language is ChromiumOS is written is ambiguous. Chromium OS consists of a variety of components coded in different languages. The kernel is a Linux kernel, therefore it's primarily written in C and some assembly. Chromium itself is written primarily in C++, with a bit of C scattered around. There are also a number of other components, such as X and the window manager, and shell scripts, and python scripts, and what not, which are written in a variety of languages.

It's not really written in anything. It's yet another Linux distribution which packages a whole bunch of pre-exisiting programs, every single one developed independently and written in whichever language its individual author prefers.

It's really just YAUD (yet another Ubuntu derivative).

If you mean Kernel and Libraries, they are written in C and Assembly.

Poke around /etc/ in Chromium, and you'll quickly see it is mostly Ubuntu; Google contracted with Canonical to do the majority of the work.

It boots quickly because it doesn't do much. :) I'm sure there's more to it than that, but restricting what the system can do is a great way to reduce the boot speed problem to something more tractable.
