ReactForge•100 Machine Coding ChallengesLearn React by building, not by watching.
Sharpen your skills with hands-on practice. Solve 100 practical React coding tasks with interactive state, real evaluation criteria, and clean source code.
From JavaScript to Machine Coding Mastery
Follow this connected progression path: bring your JavaScript foundations and master the 3 in-lab stages across 100 tasks.
JS Foundations
Variables, Arrays, Functions & DOM
ES6+ Syntax
Arrow functions, .map(), Destructuring
Stage 1: State & UI
40 Tasks: Password Gen, Todo, OTP, Modal
Stage 2: APIs & Hooks
35 Tasks: Autocomplete, Infinite Scroll, Multi-Step
Stage 3: Architecture
25 Tasks: Undo/Redo, Virtual Table, Kanban
Everything You Need to Know
Transparent requirements and real skills you will build across the 100 tasks.
The Purpose
To complement concept learning with active coding practice. By solving tasks independently, you develop real muscle memory for handling state, props, and UI events.
Prerequisites
You only need basic JavaScript ES6 (arrow functions, .map(), destructuring) and basic HTML/CSS. You start immediately with Stage 1 tasks!
What You Master
Master immutable state updates, custom hooks (useDebounce), async REST calls, virtual lists, and production-ready component patterns.
