Build the state engine behind Redux and Vue signals, with subscribe, dispatch, and reducers, then watch a single change ripple out to everything that cares.

What you'll be able to build

Build the state engine behind Redux and Vue signals, with subscribe, dispatch, and reducers, then watch a single change ripple out to everything that cares. Along the way you pick up real, transferable JavaScript skills, not just this one project:

  • closures for private state
  • the observer/pub-sub pattern
  • pure reducer functions (state, action) => state
  • subscriber callbacks and unsubscribe
  • immutable updates with spread
  • deriving computed/selector values

A course like this one

Yours is built from your own placement, so module count and depth will differ. This map shows what a intermediate-level JavaScript learner building Reactive Store actually gets.

  1. Module 1: JavaScript Values and Product State5 lessons

    Builds the component state for your reactive store.

  2. Module 2: Arrays, Objects, and Client Data5 lessons

    Builds the client data model workflow for your reactive store.

  3. Module 3: Events, Branches, and UI Decisions5 lessons

    Builds the event rule that powers your reactive store.

  4. Module 4: Functions, Modules, and Tests5 lessons

    Builds the reusable utility function for your reactive store.

  5. Module 5: API Boundaries and Async Thinking5 lessons

    Builds the API adapter for your reactive store.

  6. Module 6: Frontend Launch Readiness3 lessons

    Builds the release checklist for your reactive store.

How the lessons actually work

Every lesson has you predict what a piece of JavaScript code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Reactive Store, and a runnable proof page tied to your own code.

Common questions

How long does the Reactive Store: Redux From Scratch course take?

about 7 hours, across 6 modules and 28 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.

Do I need experience?

Some. This is an intermediate-tier JavaScript project, so it assumes you're comfortable with JavaScript basics and pushes past them.

How much does it cost?

$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.

No subscription. Module one is free.
