object-design | Style guide for object oriented design | Architecture library

I am trying to get better understanding of what the "context" object is in Vuex.

The context object is referred to numerous times in the Vuex documentation. For example, in https://vuex.vuejs.org/en/actions.html, we have:

Action handlers receive a context object which exposes the same set of methods/properties on the store instance, so you can call context.commit to commit a mutation...

I understand how to use it, and also that we can use destructuring if we only want to use the "commit" from the context object, but was hoping for a little more depth, just so I can better understand what is going on.

As a start, I found a couple ~8.5 year old posts on the "context object" as a pattern: what is context object design pattern? and Can you explain the Context design pattern?

However, specifically to Vuex, I'd love a better understanding of:

1. What is the context object / what is its purpose?
2. What are all the properties/methods that it is making available to use in Vuex?

Thank you!
