import keys from "./keys";Computes the list of keys that are different between two objects.
export default function changed(a, b) {Compute the keys in object a and b.
var keysA = keys(a),
keysB = keys(b);Find the unique set of properties comparing a to b and b to a.
return unique(
keysA.filter(n => a[n] !== b[n]).concat(keysB.filter(n => a[n] !== b[n]))
