What Is React And How Does It Function?

We are going, to begin with, the basics today. Understanding what exactly React is and why it should be used is important. There are various parts of react templates and the overall ecosystem that needs to be understood. Gradually one will be able to understand the other concepts, terms, and also underpinnings of how the framework functions. Let’s begin!

What Is Meant By React?

React is a JavaScript library that is used for building UI. For web applications, this offers the view layer. At the core of all applications of React are its components. Now the component is a module that’s self-contained and offers some output. One can also write elements of the interface on react themes like the input field or a button that works as a component. It can include anywhere from one to a higher component for the output.

When we speak broadly, for writing apps we need to write on different components of the react dashboard. And all of this has to be corresponding to carry interface elements. Then these components are organized for higher component levels that are defining the application structure.

More importantly, each of these components on the react dashboard also abides with the strict principles linked with data management. The interactive, complex user interface is also involved with the application state and complex data. React surface area is limited and has been aimed at giving you the tools for anticipating the way the application is going to look with specific circumstances set.

How to use React?

As we mentioned already, React is the JavaScript framework. It can be considered as simple as the inclusion of JavaScript with the HTML and the use of React exports with the application that you have. Honestly, it can seem a bit scary or some people, but once you get the basics right this will save you a lot of time.

How Does React Work?

Not like other predecessors, React operation is not with the browser DOM instantly. But this is via virtual DOM. This can be seen as document manipulation in the browser after the data is changed. This process can be a bit slow as the DOM is developed and run completely in memory. After one updates the virtual DOM, React can intelligently determine the changes that have been made for the actual DOM of the browser.

Understand that React Virtual DOM is present completely on the in-memory and the representation of the DOM of the web browser. With this whenever you will write the React component, you won’t be writing it directly on the DOM, but the virtual element that Reacts is going to turn into DOM.


There are some other specific steps that one should follow to understand how to react works. For this, you need to have an environment set that has syntax like XML and JSX as React runs on that. Some various tutorials and documents need to be learned then for making sure that you are on the right track.
