How to understand the vue 3 Reactivity API: Core?

The Vue 3 Reactivity API: Core is a set of functions and utilities that Vue uses under the hood to handle reactivity. Reactivity is the ability of Vue to automatically detect and react to changes in data, and update the DOM accordingly.

At the core of the Reactivity API is the reactive function. This function takes an object as its argument and returns a "reactive proxy" of that object. Any changes made to the reactive proxy will automatically be reflected in the original object, and vice versa. This is because the reactive proxy is essentially a "wrapper" around the original object that intercepts any changes made to it.

The Reactivity API also includes other functions like computed, watch, and effect. These functions allow you to create "computed properties" (which are essentially functions that automatically update when their dependencies change), and "watchers" (which allow you to react to changes in specific data properties).

Overall, the Vue 3 Reactivity API: Core provides a powerful set of tools for handling reactivity in Vue applications. By using these tools, you can create dynamic and responsive user interfaces that automatically update in response to changes in your data.
