This is a first cut of a simple JSON diff utility, inspired by the usefulness and simplicity of trentm/json.
Install node.js, then simply call the script on two JSON files, like so:
jsondiff left.json right.json
ISC. See the header in the source.
Left:
[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]
Right:
