Is this course hands-on, or is it mostly lectures? +
This is live, instructor-led training with hands-on cloud labs throughout. You'll build real React applications and work through guided exercises with your trainer present to support you.
Will I build a real project I can show employers? +
Yes. You'll work on a capstone project during the course that demonstrates your React skills. This project becomes part of your portfolio and helps you showcase your abilities to potential employers.
What's the difference between class components and functional components with Hooks? +
Class components use lifecycle methods and state directly in a class structure. Functional components with Hooks use the useState and useEffect Hooks to manage state and side effects in a simpler, more modern syntax. This course teaches both, so you can work with either pattern.
Does the course cover testing React applications? +
Yes. You'll learn to test React components using the Jest framework. Testing ensures your components work correctly and helps you write maintainable code for production applications.
How do you handle application state in React? +
You'll learn multiple approaches: component state for local data, lifting state up to share data between components, and Redux for managing complex application state across your entire application.
What's included in the Redux module? +
You'll learn Redux concepts including actions, reducers, and the data flow cycle. The course covers how to connect React components to Redux, use Redux DevTools for debugging, and manage application state efficiently.
Will I learn about API authentication? +
Yes. You'll learn token-based authentication with JWT, how to securely fetch data from REST APIs, and how to implement protected routes so only authenticated users can access certain parts of your application.
Does the course cover routing in React applications? +
Yes. You'll learn client-side routing using React Router, including route configuration, dynamic routes, route parameters, and how to navigate between multiple views in a single-page application.
Do I need to know React before starting? +
No. This course is designed for people new to React. You do need basic familiarity with HTML, CSS, and foundational JavaScript knowledge including variables, functions, and control flow.
What JavaScript skills do I need? +
You should understand variables, functions, and control flow statements. Knowledge of ES6+ features like arrow functions, async/await, and array methods is helpful but will be covered as you progress through the course.
Do I need Node.js installed before the course starts? +
Yes. You'll need Node.js installed locally on your machine to build React applications and run the development tools. Install it before your first session.
What code editor should I use? +
You'll need a code editor such as VS Code installed on your machine. VS Code is widely used for React development and integrates well with the tools you'll learn.
Can I take this course if I'm a complete beginner to programming? +
No. You need foundational JavaScript knowledge including variables, functions, and control flow. If you're new to programming, consider learning JavaScript fundamentals first.
What is React and why is it used for web development? +
React is a JavaScript library for building interactive user interfaces. It uses a component-based architecture where you break your UI into reusable pieces. React efficiently updates the display when data changes using the virtual DOM.
What is the virtual DOM and how does it work? +
The virtual DOM is a lightweight copy of the real DOM that React maintains in memory. When state changes, React updates the virtual DOM first, compares it to the previous version, and then updates only the changed parts of the real DOM. This makes applications faster.
What are React components and why use them? +
Components are reusable building blocks of a React application. Each component manages its own structure and logic. Component-based architecture makes code more maintainable, testable, and easier to understand.
How does JSX work in React? +
JSX is a syntax extension that lets you write HTML-like code in JavaScript. It looks like XML but gets compiled into JavaScript function calls. JSX makes it easier to describe what your UI should look like.
What are props and how do you pass data between components? +
Props are how you pass data from a parent component to a child component. They are read-only and flow in one direction. You pass props like HTML attributes, and the child component receives them as an object.
What is component state and when should I use it? +
State is data that a component manages internally and can change over time. Use state for data that affects what the component displays or how it behaves. When state changes, React automatically re-renders the component.
What are React Hooks and why are they important? +
Hooks are functions that let you use state and lifecycle features in functional components. Common Hooks include useState for managing state and useEffect for side effects. You can also write custom Hooks to reuse logic across components.
What are lifecycle methods and how do they work? +
Lifecycle methods are functions that run at specific points in a component's life: when it mounts, updates, or unmounts. Class components use methods like componentDidMount and componentDidUpdate. Functional components use the useEffect Hook instead.
How do you handle forms in React? +
You can use controlled components where React manages form input values, or uncontrolled components where the DOM manages them. The course covers both approaches so you can choose the right one for each situation.
What is Redux and why would I use it instead of just managing state in React? +
Redux is a state management library that helps you manage complex application state in one central place. Use Redux when your app has many components sharing data or when state logic becomes hard to follow. It makes debugging easier with tools like Redux DevTools.
How does React Router help build single-page applications? +
React Router lets you build single-page applications with multiple views without reloading the page. It handles client-side routing, so users can navigate between different sections of your app smoothly while the page stays responsive.
What's the difference between calling an API in a component and using async/await? +
Both fetch data from a server, but async/await is cleaner syntax. You'll learn to call REST APIs securely using async/await in useEffect, handle responses, and manage loading states as data arrives.
How do I protect routes so only logged-in users can access them? +
You implement protected routes by checking if a user is authenticated before rendering a component. This typically uses JWT token-based authentication. If the user isn't logged in, you redirect them to a login page.
What are custom Hooks and when would I write one? +
Custom Hooks are functions that reuse stateful logic across components. Build one when you find yourself repeating the same state or effect logic. Custom Hooks keep your components cleaner and make code more reusable.
What jobs can I get after completing this React course? +
You can pursue roles including React Developer, Frontend Engineer, JavaScript Developer, UI Engineer, Full-Stack Developer, and Web Application Developer. Many companies actively hire developers with strong React skills.
What's the difference between a React Developer and a Frontend Engineer? +
A React Developer specializes in building applications with React. A Frontend Engineer has broader skills and may work with React, other frameworks, design systems, and performance optimization. Frontend Engineers often have more experience.
Will this course help me transition into web development? +
Yes. If you have foundational JavaScript knowledge, this course teaches you modern patterns and real-world skills that employers look for in frontend and React developers. The capstone project gives you work to showcase.
How much does experience matter for React Developer salaries? +
Pay rises sharply with experience and specialization. Entry-level React Developers earn less than mid-level Frontend Engineers, who earn significantly less than senior JavaScript Developers. The salary breakdown for your region is shown on this page.
Do I need to know other frameworks to get hired as a React Developer? +
No. Strong React skills alone open many opportunities. However, understanding how React relates to other tools and learning to solve problems well increases your value to employers.
Is demand for React developers high? +
Yes. Demand for React skills has consistently outpaced supply. Many companies use React for their applications, so developers with proven React abilities have good career prospects.

No — once earned, it's yours permanently and doesn't expire. You also keep your learning materials to reference throughout your career.
How is the course delivered? +
It's a live, instructor-led online course with hands-on cloud labs — not self-paced video. You attend scheduled sessions with your trainer and classmates, ask questions in real time, and work through labs in the cloud.
How does this compare to a self-paced course? +
The difference is live, instructor-led sessions with a real cohort — real-time help, feedback, and accountability, instead of videos you work through alone. You still keep the recordings and materials, but the live guidance is what keeps you moving.
Is this the same as a university degree? +
No — it's a focused, practical, industry-oriented programme, not an academic degree. You build job-ready skills through live training and hands-on projects, and earn a Greater Insights certificate to show employers. It complements a degree rather than replacing it.
Can I attend if I'm in a different time zone? +
Sessions run at scheduled times (shown on this page). The course is fully online, so you can join from anywhere — check the schedule to confirm the timings work for you, or ask a learning advisor about alternative cohorts.
How much time do I need each week, and can I do it while working full-time? +
The live online format is built for working professionals — sessions are scheduled to fit around a job. Alongside the live sessions, set aside focused time for hands-on labs and practice; your trainer outlines the weekly commitment during onboarding.
What software or equipment do I need? +
Just a computer with a stable internet connection and a web browser. The course runs on cloud labs, so tools are provided online — no heavy local setup. You'll work with the tools your programme uses entirely in the cloud.
What support do I get during the course? +
You work directly with a live instructor throughout. Ask questions during sessions, collaborate with classmates on labs, and get feedback on your work. If you fall behind or hit a technical issue, your trainer and the Greater Insights team help you catch up.
Are sessions recorded — what if I miss one? +
Live attendance is where the real learning happens, so try to attend. If you must miss a session, tell your trainer in advance — your learning materials (and recordings, where available for your cohort) help you catch up. Ask your learning advisor about recording access.
How much does the course cost, and what payment options are there? +
The current fee is ₹12,600, with EMI options from ₹1,138/month. You can also request a quote or talk to a learning advisor for the latest pricing and plans.
Can I get a refund if it's not the right fit? +

Building interfaces for government portals, enterprise service dashboards, and large-scale IT delivery platforms are the kinds of problems React.js puts you in a position to solve across Delhi NCR. When central and state agencies commission digital products — citizen-facing services, data reporting tools, procurement systems — you are expected to deliver fast, maintainable front-ends that handle complex state and real-time data without breaking under scale. On the private side, the IT services firms concentrated in Gurgaon and Noida run delivery operations for global clients, and you are routinely expected to own the front-end layer of those engagements end to end. React.js sits at the intersection of both markets: the public sector's growing appetite for modern web applications and the enterprise delivery machine that needs engineers who can ship production-grade interfaces reliably.

Employers in Delhi NCR that recruit for React.js skills include HCL and Tech Mahindra, both of which hire front-end engineers across their large delivery operations in the region. Nagarro, with a significant presence in the NCR market, employs React.js developers on product-style engagements, while Adobe recruits for more specialised front-end roles tied to its product and engineering functions.

Demand for React.js roles in Delhi NCR grows year on year, driven by the expanding volume of both enterprise delivery work and public-sector digitalisation projects. Whichever part of the region you are based in, live online instructor-led batches run in IST, so you can join and learn without relocating.
