Atom is an open-source and free text/source code editor for Linux, Mac and Windows developed by GitHub, written in Node.js and embedded Git control. Atom is based on Electron and built using web technologies (HTML, JavaScript, CSS, and Node.js integration.). It is known as hackable text editor because it can be deeply customized and its functionality can be extended using packages built and maintained by community. It can also be used as an integrated development environment (IDE).
