As you can see, any of the existing data bindings will work, meaning updates and interactions with these variables will function correctly. However, if you try to add a new variable to the data object after its initial definition, it won't be picked up by Vue's reactivity system. This limitation leads to the scenario where:

Existing data bindings work fine

New data bindings do not trigger changes

This can be particularly limiting in dynamic applications where content and data can change frequently based on user interactions.

Step-by-Step Guide

Identify your target object: Make sure you have a designated object within your data to serve as the basis for your dynamic properties. For example:

This command does the following:

It adds a new property named my_new_value to the global object within data.

The value of my_new_value is set to 10.

It ensures that my_new_value is reactive, meaning you can bind, watch, and manipulate it just like any other property in your Vue data.

Binding and Manipulating New Variables: Once you have added the new property, you can freely bind to it in your templates, just like any other data property. For instance, to display the new value in a Vue template:

Summary

Ensure properties are added to an existing reactive object to maintain reactivity.

Once added, you can easily bind and manipulate the new properties as needed.
