ReactJS is a widely used JavaScript library for UI development. It empowers web and mobile applications for leading enterprises like Facebook, Netflix, and Airbnb.
But why does React JS appeal to developers so much? This blog post will examine the various advantages of React JS and explain why it has emerged as the preferred technology for creating fantastic user experiences.
What is the Main Purpose of ReactJS, and What Makes it Useful?
It is crucial to comprehend ReactJS’s primary goal before delving into the specific benefits of ReactJS. At Facebook, React JS was developed to address two main issues:
- Crafting scalable web applications with persistent data changes
- Building reusable User Interface (UI) elements and components
ReactJS is not a full-featured framework like conventional MVC frameworks. This JavaScript library is dedicated to creating views for mobile and online applications. React JS excels at managing and smartly dealing with the visual layer.
React JS gives developers the tools to create rich interfaces without getting stuck in intricate framework code designed for UI programming. This scenario is exactly what the needs of today’s sophisticated and high-performing web applications are.
The main purpose of ReactJS is to enable developers to craft complex UIs out of small isolated components. These components can be shared across views, reused throughout an application, and easily pass data between one another. The result is higher developer productivity and easy-to-use web apps that provide exceptional user experiences.
What are the Major Advantages of React JS?
Now that React JS’s purpose is clear let us explore the specific React JS benefits that make it so crucial:
1. Reusable UI Components
As a component-based library, React JS encourages developers to divide UI elements into isolated reusable components. This includes buttons, menus, comments, blog posts, and virtually anything visually appealing. By embracing this component mindset, developers can easily reuse and share bits of UI code across their apps.
So, rather than rewriting the same elements repeatedly, components provide a way to describe an element once and reuse it everywhere.
For example, a news feed, event listing, and messaging thread may all display profile pictures for each user. Instead of coding up a new profile picture block three separate times, developers can create a reusable component.
This single component can render a profile picture wherever needed across the app. Thus, components become Lego bricks for crafting complex UIs.
2. Declarative Programming
React JS utilizes a declarative programming style that specifies what should happen visually without prescribing complex logic. The key advantage is increased development speed and cleaner code.
For example, developers manually update the Document Object Model (DOM) with authoritative JavaScript anytime data changes occur. This requires verbose logic and DOM manipulation code to synchronize the app state with the visuals.
The Document Object Model (DOM) links web-based pages to scripts by presenting the overall structure of a document.
In contrast, React’s declarative style allows developers to specify UI as a function of the underlying data state. When the state changes, the UI automatically re-renders without manual DOM updates.
This frees developers to focus on the data flow rather than dealing with the DOM. Declarative programming replaces dozens of code lines with a few UI declarations. The result is faster development cycles and more readable and maintainable code.
3. Virtual DOM
Related to its declarative approach, React JS utilizes a Virtual DOM to optimize component rendering. Under the hood, React JS keeps a lightweight JavaScript representation of the actual DOM tree. Anytime component state changes and the UI needs updating, React JS compares the current Virtual DOM against a fresh Virtual DOM to determine the most efficient way to update the real DOM.
By diffing the Virtual DOMs, React JS knows exactly which DOM elements changed without needing to re-render everything. This incredibly fast reconciliation algorithm powers React’s exceptional rendering speeds, especially for complex UIs with frequent data changes. The Virtual DOM enables buttery smooth interfaces that delight the involved user base.
4. Unidirectional Data Flow
React JS enforces a strict unidirectional data flow between components rather than bulky two-way data binding. State is passed down from parent to child components through immutable props. Child components send data back up by triggering callbacks in parent components.
This predictable cycle ensures no confusing side effects from components directly mutating each other’s state. Unidirectional flow makes apps far easier to debug while facilitating cleaner modular components. State management solutions like Redux build upon this pattern to further enforce predictability and debuggability in the front end.
5. Cross-Platform Code Reuse
A huge benefit of ReactJS is code reuse across platforms. Components written with React Native look nearly identical to React web components. This seamlessly allows the sharing of component logic between a website, iOS, and Android development.
Given the costly nature of multi-platform development, React’s cross-platform capabilities provide huge time and cost savings. Rather than rewriting an entire app multiple times, shared components enable a learn once, write anywhere approach.
6. Active Open-Source Community
As an open-source project steered by Facebook, React JS enjoys constant development by a massive global community. This manifestation as passionate open-source software rather than a commercial platform ensures React JS will continue evolving to meet user needs rather than shareholder interests.
The thriving community fuels React’s rapid growth with third-party libraries, tools, educational resources, and more. Developers can tap this vibrant ecosystem knowing they have endless support in building whatever they can imagine.
7. Corporate Backing
While community-driven, React benefits massively from Facebook’s corporate backing. With unlimited resources and top engineering talent devoted to supporting it, React JS has rapidly improved since its 2013 open-source release. Facebook depends upon React internally across countless web properties and mobile apps.
As such, millions in ongoing investment will ensure React remains a state-of-the-art solution for crafting UIs well into the future. The resources Facebook continues pouring into React give developers supreme confidence in the long-term viability of React skills and career growth.
Why is React JS Better Than Other Libraries and Frameworks?
Given the multitude of JavaScript view libraries available today, like Vue, Angular, Ember, etc., what specifically elevates React above the competition?
While personal preference enters the equation, React JS does enjoy some clear technical advantages:
| ReactJS Tech Advantages Matched with Other Frameworks | Brief Exploration |
| Blazing Fast Rendering Speed | React’s intelligent diffing algorithms and virtual DOM optimize UI updates for maximum speed |
| True Encapsulation Via Components | Components fully isolate complexity, enabling cleaner code and reusability |
