Describing the params list:

object: The target object from who we want to read the previous value for the given path. Default value empty object.

diffs: Array of differences ordered from most recent to least recent, diffs[0] is the most recent one (Default value empty array). Each difference is an object with the following keys:

• path: [mandatory] A string following the JSON Pointer format defined by the RFC 6901

The best way to se examples, is to check the file index.test.js. There you are going to fully understand how this works, and you can understand even beyond if you read the implementation, because it is fully commented.
