Pioneered by Facebook and released as an open source; the official statement of React is that “It’s a JavaScript Library for building User Interfaces”.

This obviously has two meaning, let’s get them first.

React is a JavaScript library and is not a framework. React does not assume anything but focuses on one thing as that is to the thing is good. The thing which React does well is the second part of the definition; building User Interfaces. A user interface is what we put forward to the user when they talk with the machine. User interfaces are everywhere from the dashboard to the button on the microwave.

Creating interactive user interfaces is now a growing necessity in the modern business world. The online stores are now everywhere, web and mobile, and the main emphasis of the developers working on React is to provide the best effort to make it perfect. React is an open source JavaScript and it really HOT now for businesses.

Justification

Just as the framework is popular and fun to use, this Facebook module doesn’t allow to make and bulletproof justification as to why REACT is the best choice forever. Businesses do not have much of a choice and they are just concerned about their business justification when you really need a GO.

So, when the businesses ask the developer “Why to React”, we can just provide them the justifications:

• React’s easy to translate designs into the codes and the components can be reused across the app to save time and cost.

• React has the sticking power as it is an eternity in the JavaScript.

• Even if the throne is taken away by some competing framework, the popularity of React is enough that developers will carry it forward.

• React is used by large companies like Facebook, Walmart, PayPal and many more.

• The community is large and supportive.

Apart from the justifications, React also has three design concepts that drive it through.

1. The use of reusable components

In React, the using components are the User Interfaces. Simple functions in other programming languages can be the components and we use these components to compose the bigger functions from the smaller ones.

2. Nature of updates

React is the simple explanation for this concept. When the inner state of the component changes, the User interface automatically changes as it represents, so this change in the User interface is reflected in the device.
While working in the browser, we need to regenerate the HTML to DOM while React does not need to reflect the changes, React automatically update the DOM when needed.

3. Virtual representation in memory

With react, the HTML is written using the JavaScript and is relied on the power of the JavaScript to generate the HTML and work with the data. Enhancing the HTML framework is what other Java frameworks do.

Final thoughts

React has undoubtedly influenced the front-end world and as Facebook is cool, React is a built-in cool framework.

Learning React can be a struggle----- so does library and tools!
