+$ cat some.json | j '_.map(x => x.timestamp)' --file pre.js --tab 2
+$ cat some.json | j '_.map(x => x.timestamp)' > some.json
+$ cat some.json | j '[_].map(x => x.some_property + '👍')[0]'
+$ cat some.json | j '_.map(x => new Date(x.timestamp).toISOString())'
+$ cat some.json | j --file preload.js '_.map(x => x.timestamp)'
+$ http https://swapi.co/api/people/ | j 'Object.keys(_)'
