app-state-utils
Version:
A set of utilities for state management in web apps, integrates well with front-end state management libraries like redux and vuex, and can be used on server side as well. It defines methods for mutating keys and values in a conventional javascript object

* @fileoverview : Exports a function: deleteEntry(state, payload)
*
* @function deleteEntry : For state drilling and surgical deletion of object [key: value] pairs.
* This function can be used to dynamically delete infinitely nested object entries.
* It takes current state and a payload object as arguments.
* It returns a local function which returns updated state.
*
* @param {Object} state The object to be mutated.
* @param {Object} payload { name: String, child: Array }
* @param {String} payload.name Name of the [key: value] pair to be deleted or second object in the nesting hieriarchy.
* @param {Array} payload.child Array of strings pointing to the nested [key: value] pair to be deleted.
* @returns {Function} (local function) (payload) => : The new app state, or current state if it was not altered.
