You may not know that jq is a Turing-complete combinator language that lets you define custom filters using either imperative or functional control structures.

Maybe that time when you piped a bunch of commands together and jq was one of them, you could have spared a few of the others?

The format of this workshop:

• We decide together upon some useful or fun JSON processing p… Read more
