FAQ on React JS:
What is React JS?
React JS is an open-source JavaScript library used for building user interfaces, primarily for single-page applications.
How does React differ from other JavaScript frameworks like Angular or Vue?
React is more focused on the view in the MVC model and is often considered a library rather than a full-fledged framework. Unlike Angular or Vue, it only handles the UI part and can be integrated with other libraries.
What is JSX?
JSX stands for JavaScript XML. It is a syntax extension for JavaScript and is used with React to describe UI elements.
Why is React’s virtual DOM beneficial?
The virtual DOM allows for efficient updates and rendering, as changes are first made to the virtual DOM and then the real DOM is updated selectively, improving performance.
What are React hooks?
Hooks are functions that allow you to “hook into” React state and lifecycle features from function components.
How do components communicate in React?
Components in React communicate primarily through props, but context and hooks like useContext can also be used for more global data.
What is Redux and how does it relate to React?
Redux is a predictable state container for JavaScript apps, often used with React to manage application state across components.
Can React be used for mobile app development?
Yes, with React Native, a framework derived from React, developers can create native mobile applications.
What is a React Fragment?
Fragments let you group a list of children without adding extra nodes to the DOM.
Why are keys important in a list in React?
Keys help React identify which items have changed, are added, or removed, and thus give a stable identity to elements, making the rendering process more efficient.
FAQ on the Course:
Is this course suitable for complete beginners?
Yes, the course is designed to cater to learners of all levels, from freshers and beginners to experienced developers.

Absolutely! Once enrolled, you’ll have unlimited access to all course materials, including any future updates.
Are there any prerequisites for this course?
Basic knowledge of JavaScript is recommended, but the course starts with foundational React topics, making it accessible to most learners.
How are the coding challenges structured?
Coding challenges are designed to simulate real-world scenarios and test the application of knowledge gained in the course.
Is there a certificate provided after course completion?
Yes, upon successful completion of the course, you’ll receive a verifiable certificate showcasing your expertise in React JS.
Are there any interactive sessions or only pre-recorded lectures?
The course primarily consists of expert-led pre-recorded sessions, but there’s an interactive Q&A section for students to engage and clarify doubts.
Do I need any special software to go through the course?
All you need is a modern browser and a code editor like Visual Studio Code for the coding exercises.
