React learning path

I am a backend engineer in java and kotlin. I have a overall understanding how html, css, javascript works. And now I want to step into front end development world. But I want to take only necessary adequate minimum. And start slowly without jumping into lots of framework. My goal is to be ok with react, with side tools which serve react. I want to code in typescript, basically I would want to start with learning typescript. Lets build a learning plan as a bullet list and go over the list by guidance from your side, and I want to learn by doing

TypeScript & React Learning Plan

Given your strong backend experience, here's a practical, hands-on path that builds up gradually:

Phase 1: TypeScript Fundamentals (Week 1-2)

• Basic types and interfaces - Learn type annotations, primitives, and how to define object shapes

• Functions and generics - Type function parameters/returns, understand generic constraints

• Union types and type guards - Handle multiple possible types safely

• Working with arrays and objects - Map, filter, reduce with proper typing

• Async/await with types - Type promises and async functions

Phase 2: Modern JavaScript essentials (Week 2-3)

• Destructuring and spread operators - Extract values elegantly

• Arrow functions and closures - Understand this binding

• Array methods - Map, filter, reduce, find (you'll use these constantly)

• Modules (import/export) - How modern JS code is organized

• Promises and fetch API - Make HTTP calls (similar to your backend work)

Phase 3: React Core Concepts (Week 3-5)

• JSX and components - Build your first functional components

• Props and prop types - Pass data between components with TypeScript

• useState hook - Manage component state

• useEffect hook - Handle side effects, data fetching, lifecycle

• Event handling - onClick, onChange, form submissions

• Conditional rendering and lists - Display dynamic content

Phase 4: React Intermediate (Week 5-7)

• Custom hooks - Extract reusable logic

• useContext - Share state without prop drilling

• Form handling - Controlled components, validation

• API integration - Connect to REST APIs (your comfort zone!)

• Error boundaries and loading states - Handle async operations gracefully

Phase 5: Essential Tooling (Week 7-8)

• Vite - Modern build tool (simpler than webpack)

• React Router - Client-side routing

• Basic CSS/Tailwind - Style components adequately

• ESLint and Prettier - Code quality tools
