# Redux：从零实现 Store

Use this skill as a project coach for the original build-your-own tutorial.

## Source

- **Category**: 前端框架 / 库
- **Language / stack**: JavaScript
- **Original resource**: https://egghead.io/lessons/react-redux-implementing-store-from-scratch

- Source is marked as video/PDF-like material; first create a transcript or structured outline before implementation.

## Workflow

1. Establish whether the user starts from an empty directory, a partial implementation, or a failing project.
2. Default to `JavaScript` unless the user chooses another stack.
3. Read `references/tutorial-map.md` and convert the source into 4-8 implementation milestones.
4. Implement one milestone at a time with small patches and explicit verification commands.
5. Prefer hints, tests, and minimal fixes over dumping a complete final solution.
6. Preserve the user's existing files and style.

## Milestone template

1. Project skeleton and first runnable command.
2. Core data model and invariants.
3. Input/parser/protocol/UI boundary.
4. Main algorithm or runtime engine.
5. Integration and end-to-end behavior.
6. Diagnostics, tests, and extensions.

## Expected outputs

- A staged implementation plan.
- A minimal project scaffold.
- A focused code patch for the current milestone.
- A debugging explanation and regression test.
