I cannot remember the syntax and have to search for it every time but it's very powerful. You basically give a DSL to process json. I can do map, filter and even math. The reason it's popular partly because it's available from both Centos/Debian based. Just use `yum` and `apt`. Most of time, you maybe limited with what have on a container. And `jq` may even pre-install by DevOps. Second is it play well with unix tool, pipe and friend.
