Hey there! This problem might be a bit unpredictable, but give it a go and let us know how you do!

Given the JSON file

{"employees":[{"firstName":"John", "lastName":"Doe"},{"firstName":"Anna", "lastName":"Smith"},{"firstName":"Peter", "lastName":"Jones"}]}

, how would you use the command-line tool jq to sort the employee records by last name in ascending (A-Z) order?

Select one option from the list

jq 'sort(.employees[].lastName)' file.json

jq 'sort_by(.employees[].lastName)' file.json

jq '.employees[] | sort_by(.lastName)' file.json

jq '.employees | sort_by(.lastName)' file.json
