I created the exact same app in React and Vue. Here are the differences. [2020 Edition]

A few years ago, I decided to try and build a fairly standard To Do App in React and Vue. Both apps were built using the default CLIs (create-react-app for React, and vue-cli for Vue). My aim was to write something that was unbiased and simply provided a snapshot of how you would perform certain tasks with both technologies. When React Hooks were released, I followed up the original article with a '2019 Edition' which replaced the use of Class Components with Functional Hooks. With the release of Vue version 3 and its Composition API, now is the time to one again update this article with a '2020 Edition'.
