Step By Step Mastering React Course guide
Step By Step Mastering React: Free Beginner Course Guide
Learn React step by step: components, JSX, props, state, events, lists, forms, lifecycle, memo, refs and error boundaries. 31 free videos, 3.5 hours.

Step By Step Mastering React is a beginner course that teaches React from your very first project, one concept per video. It is for web developers who know some JavaScript and want to build user interfaces with React, and for students who need a structured path through components, props and state.
The course covers project setup and structure, functional and class components, JSX, props and state, event handling, conditional and list rendering, styling and forms, the component lifecycle, and advanced topics such as pure components, React.memo, refs, higher-order components and error boundaries. There are 31 videos, about 3.5 hours in total, free on YouTube and listed on the React course page.
Who this course is for
- JavaScript learners ready for their first front-end framework.
- HTML and CSS developers who want to build interactive, component-based pages.
- Students and job seekers preparing for front-end roles, where React fundamentals come up again and again.
- Developers maintaining existing React code, including class components and lifecycle methods.
The catalog marks it Beginner. You should be comfortable with basic JavaScript first. If you are not, start with the JavaScript course mentioned below.
What you will learn
1. Getting started. React Introduction, Tools For React Development, Create First React Project and React Project Structure get a project running and explain what each folder is for. Knowing the structure stops the generated files from feeling like magic.
2. Components and JSX. Components, Functional Component, Class Component and JavaScript XML JSX. Components are the basic unit of every React app. The course teaches both functional and class styles, which also helps you read older codebases.
3. Data: props, state and setState. Props, State, setState and Destructuring, plus a short video on installing helper extensions. Understanding how data moves down through props and changes through state is the single most important React idea.
4. Events and communication. Event Handling, Master Event Binding in React and Mastering Method As Props in React show how components respond to users and how a child component can call a method in its parent.
5. Rendering real UIs. Conditional rendering, list rendering, React List Rendering & Keys Explained, styling React components and form handling. Forms and lists make up most of what real applications show on screen.
6. Lifecycle and advanced patterns. A lifecycle overview, mounting and updating lifecycle methods, then React Fragments, pure components, React.memo, refs, higher-order components and error boundaries. These topics help you write components that perform well and fail gracefully. Pure components and React.memo are about skipping unnecessary re-renders, while error boundaries stop one broken component from taking down the whole page.
How the course is organised
There are 31 videos and about 3.5 hours in total. Most videos run between 4 and 10 minutes, with form handling and conditional rendering among the longest.
The course moves in this order:
- Videos 1–5: introduction, tools, first project and project structure.
- Videos 6–9: components and JSX.
- Videos 10–14: props, state, helper extensions, setState and destructuring.
- Videos 15–17: events, event binding and methods as props.
- Videos 18–22: conditional rendering, lists and keys, styling and forms.
- Videos 23–25: the component lifecycle.
- Videos 26–31: fragments, pure components, memo, refs, higher-order components and error boundaries.
How to study it step by step
- Create the first project with the video and keep it as your practice app for the whole course.
- Build one small component per lesson in that app, rather than only watching.
- After the props and state block, build a counter and a greeting card that takes a name as a prop. These two tiny apps show the difference between props and state better than any definition.
- After the rendering block, build a to-do list with conditional messages, a list with proper keys, and a form to add items.
- Watch the lifecycle videos with your to-do app open and add logging to see when each method runs.
- Finish with the advanced topics and add an error boundary and a ref (for example, auto-focusing the input) to your app.
This course currently has no Skills Pragati hands-on lab guide, practice simulation or mock exam.
Frequently asked questions
Is the React course free?
Yes. All 31 videos are free on YouTube, and the course page lists them in order.
How long does it take?
About 3.5 hours of video. If you build along with each lesson, two to three weeks of regular practice is realistic.
Do I need to know JavaScript first?
Yes, the basics. React is written in JavaScript, so variables, functions, objects, events and array methods such as map should feel familiar. Step By Step Mastering Modern JavaScript covers all of these, and the Modern JavaScript Refresher Course is a quicker review.
Does the course cover class components?
Yes. It teaches both functional and class components, and its lifecycle videos cover mounting and updating lifecycle methods, which are a class component feature.
