What’s maybe even more important, though, is that the editor’s user community has now published over 2090 Atom extensions and 660 themes.
The Atom project was started by GitHub founder Chris Wanstrath back in 2008. It was still called Atomicity back then and the idea was to use common web technologies to build an extensible code editor. As GitHub took off, though, Wanstrath set the project aside until 2011. It still took until 2014 before GitHub released Atom to the public.

As is typically the case, the 1.0 version number is meant to indicate that the project’s core is now considered stable. “Until now, work has largely gone into defining the 1.0 foundation. Now that the foundation is stable, we can shift our efforts to reaching the full potential of the platform,” the GitHub team writes today.
All of these are questions other code editor developers are also looking at, but few of them have the active developer community around them to achieve these goals. Because Atom is so modular, there are also now other projects, including Facebook’s Nuclide IDE, that use it as their core editor.
