In this lesson, we’ll learn how to read and do basic queries on JSON with jq, an installable command line tool that makes working with JSON in bash really easy. We‘ll pipe the JSON output of the Github API to jq to extract values. Note: jq has to be installed. On macOS, the easiest way to do this is to run brew install jq.
