React

React is a medium-sized framework that is a great fit for developing website front ends. It combines HTML, JavaScript, (S)CSS into JSX Components that track "props and state". It can increase your website development productivity pretty quickly. Especially with the addition of npm modules, which literally do everything under the Sun. (like, four times over, sadly...)

It can stumble through reactivity when combined with bootstrap to give mediocre mobile support with moderate code changes (I don't love bootstrap on phones, tbh).

My meta framework of choice is Vite. I used it to develop a 2023 D3 skeleton project.

Patterns

Use ES6 modules, destructuring/spread, functional components
Precisely use Promises and async/await to accomplish CHAIN, PARALLEL, and BATCH processing
Understand and abide by PROP and STATE best practices
Add and remove modules properly using npm rather than editing package*.json

npm install # on new environments
npm i --save newly-needed-component
npm i --dev newly-needed-dev-only-component
npm remove no-longer-needed-component

Bootstrap works well for breakpoint-based management of 12 columns; direct use of flex and grid is MUCH more powerful and should be considered for any complex layout

Issues

I built an Array of objects with some JSX. It would NOT allow me to use find() on it. Weird.
