jsonpointer.get(obj, '/qux/1');   // returns 4
jsonpointer.get(obj, '/qux/2');   // returns 5
jsonpointer.get(obj, '/quo');     // returns undefined

Similar packages

Other packages similar to jsonpointer

lodash.get

Lodash's get function offers similar functionality for retrieving values from a JSON object using a dot/path syntax. Unlike jsonpointer, it does not adhere to the JSON Pointer RFC 6901 standard and uses a different syntax for paths.

object-path

object-path is another npm package that provides methods to access and manipulate properties of objects. It supports both dot and bracket notation for paths, offering a more flexible syntax compared to jsonpointer's strict RFC 6901 compliance.
