Update the custom simplified version of redux to use the new context API

[horacioh]

if you go to the redux branch, there's an exercise that you need to implement your own version of redux. this version of redux is using the old context API, so the goal is to refactor the code and Implement the new version of the context API.

Files that you need to modify:

• /src/react-redux/connect.js
• /src/react-redux/Provider.js

you can follow the Official documentation here: https://reactjs.org/docs/context.html

Tasks

• refactor code in redux branch
• refactor code in redux-leanjs-part1 branch
• refactor code in redux-leanjs-part2 branch

any questions please let us know! :)
