A quick, no-nonsense guide to get you up and running with jq

json is everywhere. Many applications require reading json or transforming it. Doing this by hand is slow. Using libraries in programming languages is slow. But jq?jq is FAST. It's high performance and easy to use. And if you master jq, you will be more productive.

This is an introductory course to jq. It goes over the basics one "filter" at a time, and if you don't know what a "filter" is, there's a lesson on that too. Lessons are short, each is less than two minutes. They cover both the big idea of how a filter works and examples that you can type in YOUR command line.

So in a few minutes, you can learn a new filter and incorporate it into your daily workflow. It's perfect for watching while tests are running or on your daily commute.

This course is for anyone who works with json from seasoned professionals to those just learning to code.

jq manipulates json which is helpful for all engineers. Front end engineers can use it to debug json values from the APIs they're working with. Backend engineers need to construct json values to test the APIs they're building. Embedded engineers use jq to synthesize embedded state. jq's power is endless and universally applicable.
