React- A Roadmap from beginner to advanced

With advancements in technology, web applications have become more demanding. These applications need to be updated with time. Thus, it is quite difficult to design new applications from the basics. Hence, React is the best programming JavaScript library. That adds the changes in form of a component. Before moving towards the application development with React, let us go through the basic concept of it.

What is React?

It is a front-end JavaScript library for building fast and interactive user interfaces of web applications. The front-end library is crucial for the addition of components to recreate the new features in an application. Hence, the creation and implication of new UI complex components are unique abilities of this language, making it more demanding for the programming of applications. 

History

The invention of React was accidental, as software engineer Jordan Walke wanted to make changes in the news feed of Facebook. Then, It was first deployed at Facebook in 2011, and then on Instagram in 2012. 

How does it operate?

In heart of all the React applications are the components. These are essentially a piece of the user interface. So, when building the applications with this language. We build a bunch of isolated, independents, and usable components, and they compose complex user interfaces. Every React application has at least one component which is preferred as a root component. This component contains other trail components, every React application has a tree of components. If you have worked with Angular 2, you might have listened to it. 

Step by Step learning of React

First step; component designing

For example, let us imagine we have developed an application like Twitter, we can split the page into components, like NavBar, profile, trend, and feed. Now feed include several Tweet component and then each Tweet can contain the like component, used for other pages. Each component is a piece of UI, we can build these components separately, and can put them together to build complex UI’s. 

Second Step; Attachment of component 

In terms of implementation, a component is typically implemented as a JavaScript class that has some state and render methods. The state is data that want to display when the component is rendered. And render method is responsible for describing what the UI should look like. The output of this render method is React element which is a simple, plain JavaScript object that maps with DOM Element. It is not a real DOM element, it is just a plain JavaScript object that represents the element in memory, represented as Virtual DOM. It is cheap to create, when we change the state of the component, we get the new React element. 

Third Step; Modification of user’s interface

React will then compare this element with the previous one. It points out the change. And then, updates a part of Real Dom to save the changes. When building an application will React, unlike other JavaScript applications, there is no need to put the code. Simply attach the component and it scans the DOM element and updates. It has a small API to learn, in which other libraries are used for routing and calling HTTPS services. 

What features make it more demanding? 

 It is currently the most famous and popular JavaScript library for building user interfaces. As you can see on Google trends, React is dominating the space of libraries and frameworks for building user interfaces. Now we should have to address the features and abilities that make it more demanding among others. These abilities include as

1. Easy to learn

React is not a language but a JavaScript library that uses the coding of language to design the component. These components are easy to code by using simple HTML and JavaScript. What feature has to introduce in the application. Try to make a UI component and attach it with former coding.   

2. Efficacy 

The developers want to introduce new features in their former designed web and mobile application. It is too hard to develop the application from the basics. It is the best programming library that can implement the changes in form of a component. Like anyone who wants to introduce a video calling feature to Facebook, he will attach a new feature through React. 

3. Simple Approach

React is a plain strategy to update mobile and web applications with time. Web developing companies plan to add new features in there after every specific period. It is a simple approach in which the developer can add the component in the front end of single page application. 

4. Intuitive for applications

It is the best tool to develop native mobile applications. The React coding is reusable. So, a developer can use it to design the same application on Android, iOS, and the web with simple coding. 

Futures

It is the era of technology in which different software houses compete to introduce some new features in their applications. Sometimes, these changes are adopted to revolutionize the formerly build mobile application. So developers want to save their time and energy by using an innovative approach to reacting. 

We have learned from the blog. It is the best approach to implement the new features and changes in the front end of formerly developed applications. It operates the coding of HTML and JavaScript, so, it is convenient for an expert of these languages to learn React. Hence, a front-end developer needs to have expertise in this language. That increases its development chances in any software house.

Thus it’s all about React, providing innovation to applications with the facility of modification in them.
