The document discusses key concepts of React JS including component-based architecture, declarative syntax, virtual DOM, one-way data binding, and large ecosystem. It emphasizes that React uses reusable UI components to ease development. It also leverages a virtual DOM for efficient updates and promotes one-way data flow for predictability. Additionally, it has a large library of third-party tools that can be used.

3. Component-Based
Architecture
React emphasizes the development of reusable UI
components. This modular strategy eases the
development process, making it simpler to
maintain and update code.

4. Virtual DOM
React leverages a Virtual DOM, which
is an informal portrayal of the actual
DOM. When data evolves, react
updates the Virtual DOM first and then
effectively updates the parts of the
actual DOM that have shifted.

5. Reacts declarative syntax as introduced in the ReactJS
training programs of reputed institutes like CETPA
Infotech and others permits developers to define what
the UI must look like at any given point of time. This
makes it simpler to reason about the state of the
application by abstracting away the complexity of
updating the DOM.
Declarative Syntax

6. React promotes one-way data
flow, which minimizes the
chances of bugs and makes
debugging simpler. Data flows
from parent to child components,
guaranteeing a predictable and
manageable application state.
One-Way Data Binding

7. Large Ecosystem
The wide ecosystem of React
incorporates a vast library of third-
party libraries and tools. Developers
may use Redux for state
management, React Router for
routing, and Material-UI for pre-
designed components, among
various others.
