As we know, in Redux, the state is represented as a tree or a JSON object. At times, it becomes necessary to modify a nested object or a leaf in the tree. In order to achieve this, a destination path is provided, which points to the specific object that needs to be modified.
1. We will utilize the symbol > to indicate the specific object we intend to modify.
For example: we want to modify the name inside company inside the User. We have to write a path to go to that named object.
In this case, we use > symbol to point out
In order to see how to use the Destination Path, we can examine an example of an insert function where we aim to insert an object into a leaf node of the tree.
Example of using Destination Path
I want to insert { gps: {x,y,z} } into User>address>geo
2. If you want to traverse an item in an array, you can use the symbol | [key]=[value] to specify the particular object that you want to modify.
