go - Why is Golang written in Golang? -

-

i see go language written in golang itself. golang @ github

why done way ?

what new features ?

how build compiler ?

it's practice called self-hosting. lots of languages start out written in low-level language c make goal rewrite canonical compiler in own language before version 1.0.

it's way eat own dog food, make sure language complex piece of software needs , ensure compiler works right.
