How Does React Work?
React works by employing a combination of techniques and principles that make it powerful for building user interfaces.
Let's take a closer look at each one below.
Adopting a Declarative UI Design
React adopts a declarative approach to UI development. Instead of manually manipulating the Document Object Model (DOM) and specifying every step of the UI transition, developers simply declare the desired state of the UI.
It then takes care of updating the UI to match this state. This approach simplifies the code, making it more predictable and easier to debug.
Utilizing Virtual DOM for Performance
React uses a virtual DOM — a lightweight copy of the actual DOM to enhance performance. This allows the library to perform any DOM manipulation operations efficiently.
Each time the state of an object changes, React will first change the object within the virtual DOM. From there, it uses a diffing algorithm and then updates the real DOM with only the necessary changes rather than re-rendering the entire UI. This results in significant performance gains, especially in complex applications.
Using Components for Reusable Code
React's architecture is based on components — self-contained, reusable pieces of code that represent a part of the UI. Custom components can be nested, managed, and reused, allowing for a modular and scalable approach to app development.
These reusable components are highly efficient for developing complex applications, as they promote reusability and maintainability of code.
Receiving Data Through Props
In React, components receive data through properties, commonly referred to as "props." Props are immutable, ensuring that components can be predictable and pure.
This means components in React can receive and display initial data, but they can't directly modify the data. They can only notify changes via callbacks or events, promoting a unidirectional data flow that enhances code stability and readability.
Pros and Cons of React
React offers developers a flexible and efficient library for building UIs with a component-based architecture that simplifies development and enhances reusability. However, it also presents challenges that can complicate the development process.
Below are the pros and cons of using React.
Pros
Here are the pros of using React:
-
Reusable, maintainable components: React's component-based architecture ensures code is reusable and maintainable.
-
Improved performance with virtual DOM: The Virtual DOM in React enhances application performance, enabling faster and more efficient updates.
-
Simplified development via declarative UI: React's declarative UI simplifies the development process.
-
Extensive community support and resources: A large community and abundant resources offer substantial support for developers.
-
Cross-platform development with React Native: React Native extends React's capabilities to mobile app development, allowing for cross-platform solutions.
Cons
Here are the cons of using React:
-

-
Increased boilerplate in large apps: Larger applications may experience increased boilerplate, potentially complicating the codebase.
-
Dependence on ecosystem for features: React often relies on its ecosystem for additional features, which can be both a strength and a limitation.
