Alternatives

• catj - pretty much the same thing - https://github.com/soheilpro/catj/blob/master/catj.js - Node/NPM
• tabbyj - also similar - https://github.com/nint8835/tabbyj - Python
• gron - much more features, such as going backwards given the output of itself, which is quite neat - https://github.com/tomnomnom/gron - Go

initially inspired by catj, but without dependencies on node/npm
