What can Atom do?


Hello Everyone,
I am new to Atom and GitHub, I’ve heard that Atom is the best compiler. But I’m not quite sure what it can do.
Can someone please enlighten me with what Atom can do; what programming languages does it support; what packages are; what its functionality is? Also can someone please tell me what GitHub is and what its purpose is?

Thanks Appreciate the help


Atom is not a compiler. It is a text editor.
