## What it is
Didact is a DIY tutorial series and code repository that walks through building a miniature React from scratch, step by step, following React 16.8's architecture including fibers and hooks. It accompanies blog posts (notably 'Build your own React') with code samples and commit diffs for each step.

## Use cases
- learn how React works internally
- understand the fiber reconciliation algorithm
- build a mini React from scratch
- study how hooks are implemented
- prepare for React library interviews
- teach frontend framework internals

## When to choose
- you want a deep, step-by-step understanding of React's internals
- you learn best by implementing things yourself
- you want a self-contained guide covering createElement through hooks

## When to avoid
- you need a production-ready React replacement
- you want current React 18/19 features like server components
- you just need to build an app with React

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: frontend, web-development, tutorials
- platform: browser
- tags: react-internals, diy-guide, jsx, fiber-architecture, hooks, educational, javascript
