What Is React Development
React is a JavaScript-based UI development
library. Facebook and an open-source developer community run it. Although React
is a library rather than a language, it is widely used in web development. The
library first appeared in May 2013 and is now one of the most commonly used
front-end libraries for web development.
Why React?
React’s popularity today has eclipsed that
of all other front-end development frameworks. Here is why:
1) Easy creation of dynamic applications: React
makes it easier to create dynamic web applications because it requires less
coding and offers more functionality, as opposed to JavaScript, where coding
often gets complex very quickly.
2) Improved performance: React uses Virtual
DOM, thereby creating web applications faster. Virtual DOM compares the
components’ previous states and updates only the items in the Real DOM that
were changed, instead of updating all of the components again, as conventional
web applications do.
3) Reusable components: Components are the
building blocks of any React application, and a single app usually consists of
multiple components. These components have their logic and controls, and they
can be reused throughout the application, which in turn dramatically reduces
the application’s development time.
Features of React
React offers some outstanding features that make it the most widely
adopted library for front-end app development. Here is the list of those salient
features.
1) JSX:- JSX is a JavaScript syntactic
extension. It’s a term used in React to describe how the user interface should
seem. You can write HTML structures in the same file as JavaScript code by
utilizing JSX.
2) Virtual Document Object Model (DOM):- The
Virtual DOM is React’s lightweight version of the Real DOM. Real DOM
manipulation is substantially slower than virtual DOM manipulation. When an
object’s state changes, Virtual DOM updates only that object in the real DOM
rather than all of them.
3) Architecture:- MVC is an architectural
pattern that splits the application layer into Model, View, and Controller. The
model relates to all data-related logic; the view is used for the UI logic of
the application, and the controller is an interface between the Model and View.
4) Extensions:- React goes beyond just being a
UI framework; it contains many extensions that cover the entire application
architecture. It helps the building of mobile apps and provides server-side
rendering. Flux and Redux, among other things, can extend React.
5) Data Binding:- Since React employs one-way
data binding, all activities stay modular and quick. Moreover, the
unidirectional data flow means that it’s common to nest child components within
parent components when developing a React project.
6) Debugging:- Since a broad developer
community exists, React applications are straightforward and easy to test.
Facebook provides a browser extension that simplifies and expedites React
debugging.
Components in React
Components are the building blocks that comprise a React application
representing a part of the user interface.
React separates the user interface into numerous components, making
debugging more accessible, and each component has its own set of properties and
functions.
Here are some of the features of the Components -
1) Re-usability - A component used in one area
of the application can be reused in another area. This helps speed up the
development process.
2) Nested Components - A component can contain
several other components.
3) Render method - In its minimal form, a
component must define a render method that specifies how the component renders
to the DOM.
4) Passing properties - A component can also
receive props. These are properties passed by its parent to specify values.
