React was released in 2013. In just seven years, it has managed to be among the top JavaScript frameworks in the market. This open-source framework has grown rapidly over the last few years. If you already know JavaScript, it won’t take you long to learn ReactJS.

There are several reasons why you should learn ReactJS. Here are a few of them explaining why you should learn this framework:

  • ReactJS can be used for producing different types of web applications, avionics, command-line interfaces, native mobile apps, and much more.
  • It is extensively used by top companies like Facebook, Instagram, PayPal, Netflix, and Apple. Facebook has been using React since 2011.
  • React can be used to build complex UI. It employs a virtual DOM ensuring maximum efficiency. It does this by re-rendering nodes whenever required.
  • Learning ReactJS is easy. If you have a good command over JavaScript, it will only take you a few hours to get a strong grasp over ReactJS.
  • With React, you will have the support of a large community of developers. It is extensible and developer-friendly which makes it a top choice for new developers.
  • React is considered to be very scalable. React’s modular nature has led to the growth of the framework. You can write different parts of applications independently and reuse them in a project or outside.

Learning the basics of ReactJS can take you anywhere between 1 to 6 months.

The time required for mastering React will depend on the time you are dedicating to learning and your prior experience in the field of software development. So, if you spend about 10 hours every week learning the framework, you will be able to use the library quicker than someone who practices React for only a couple of hours. Spending just two hours every day in learning React will help you in mastering the fundamentals in a few months.

If you already have a basic knowledge of JavaScript, it will only take you a few days to get started with React. However, mastering React is a different aspect. The time required to become an expert in it will depend on how much time you are dedicating to the framework. Making the most out of the library will require several months of practice.

There is one upside to learning React. The learning process is not like the traditional fields where it takes months and years of book learning and practical experience to complete the educational experience. React has an active learning process which means that after you have completed a few months of basic training, you can start working on React and then continue to learn on the job.

Through ReactJS, you will be able to leverage the tool to create responsive and engaging UIs. Here are some other incentives for learning ReactJS:

  • ReactJS library deals with only the view layer and is lightweight. With just a basic understanding, you will be able to build web apps.
  • React has a component-driven structure meaning smaller components within a wrapped component. You can reuse the components for ensuring a consistent appearance to the app. This makes building large apps easy as you can strategically structure the components.
  • ReactJS uses virtual DOM that is maintained in memory. Any change in the view is first communicated to the virtual DOM that triggers a differential algorithm to compare the earlier and present states of the virtual DOM. Also, it calculates the leanest manner possible for applying the changes with the least number of updates.
  • By using ReactJS, you won’t have to learn the complex internal mechanisms such as digits cycles. To build forms, you will have to learn the life cycles of states, props, and components. This increases your productivity in architecture design.
  • You can avail of the React Developer tools as a Chrome Extension. These tools help in viewing the corresponding props and states and inspecting hierarchy embedded React components.

The average annual salary earned by a ReactJS developer is ₹733,000.

If you are an entry-level developer with less than one year of working experience with ReactJS, you can earn about ₹400,000 per annum. Early-level developers with about 1 to 4 years of working experience can earn an income of ₹540,000 per year. As a mid-level ReactJS developer with between 5 and 6 years of working experience, your salary can be about ₹1,300,000 per annum. As your skills and experience grow and you become a senior-level developer, your earnings will increase dramatically, reaching more than ₹1,700,000 per year in India.

Most people start as a front-end web developer and then transition into full-stack developers, that combines frontend and backend development. As a full-stack developer, you will have job opportunities with big corporations and small startups as you will have a deep understanding of design and development.

React Certification and Training

React Training

React v16.0 has some major updates and changes to the core algorithm. Here is a brief introduction to the changes:

  • New Core Architecture - React 16 is built on Fiber, a new core architecture.
  • Fragments and Strings - Return a string or an array of elements from the component's render method.
  • Error handling - Through Error Boundary.
  • Portals - Allows rendering children in any DOM node regardless of their location.
  • Server-Side Rendering - Completely rewritten server render that supports streaming.
  • Reduces file size - Smaller than 15.6.1.

There are several benefits of getting trained on React. Here are the main benefits:

  • React is simpler to understand because of its well-defined lifecycle, component-based approach, and use of plain JavaScript.
  • Anyone with a basic knowledge of programming can understand React easily.
  • You can use React Native for creating mobile applications.
  • React uses an application architecture called Flux and one-day data binding to control the flow of data through one control point, dispatcher. This makes it easier to debug self-contained components.
  • Testing React applications is super easy.

Like any other language, you will have to spend a lot of time learning and practicing becoming a React developer. Here is how you can get started:

  • Have a basic knowledge of HTML and JavaScript.
  • Understand the fundamental concepts of React through online tutorials or training programs. You can check out the KnowledgeHut’s training program on React.
  • Once you are familiar with the basic concepts, you can start working on small web applications that will help you get an in-depth understanding of the subject. Make sure that you focus on the concepts that you have learned along with the best practices.
  • Participate actively in open forums and try to answer as many questions as you can. If you are not able to answer, you can follow the question and try to understand the problem and solution.
  • Today, you can get a lot of code online. Keep practicing and if you are stuck somewhere, you can always google it.
  • Keep practicing as much as you can.

React is a high-powered tool that should be used for specific projects. You can use it in projects that have many components with often changing states, navigation items, dynamic inputs, user login, access permissions, active/disabled buttons, expanded/collapsed accordion sections, etc.

  • Social media app - It should have features like the ability to post text and media files, a live feed, user authentication, and enabling other users to like or comment on the posts.
  • E-commerce app - It doesn’t have to be big. A smaller and more focused Ecommerce app will do the job. It must have a storefront, products, shopping cart, and a checkout process.
  • Entertainment app - Think of the media that interests you and build a simple platform where users can log in and save the content they like. You can also add other social elements such as likes, comments, and shares.

React is one of the most popular frameworks out there for the following reasons:

  • With it, developers can write their apps within JavaScript.
  • Components help developers in breaking down complex UI.
  • Through Props, you can populate components using custom data.
  • The state can be used for storing all the changes in a single section.
  • The usage of virtual DOM makes the app run faster.

It is easy to learn, especially if you are a developer and have some experience in writing code. However, the problem is with the ecosystem around it. Before you write even a single line of code, you need to:

  • Install NodeJS.
  • Create a npn project.
  • Install different libraries that are not related to your project but are needed to enable the usage of JS ‘bling’.
  • Install Babel dependencies for dealing with React and JSX.
  • A compilation step for the non-compiled languages.

Here is the roadmap to learn React:

  • Prerequisites - Basic knowledge of HTML, JavaScript, CSS, Es6 features, and how to use npm.
  • Read the official documentation by React.
  • Use online code editors for practicing or setting up a development environment.
  • Start building projects like a simple calculator app, to-do app, shopping cart, etc.
  • Learn about React Router that helps in creating routes to the single-page applications.
  • Go for projects like a Hacker News clone or a simple CRUD application.
  • Learn more about Webpack (JavaScript module bundler), Server Rendering (to create components in the server and render as HTML in the browser), and Redux (JavaScript library used to maintain application states).

React is a JavaScript library that is used in web development for building interactive elements on the website.

Here are some ways beginners can get started with React:

  • Learn React - Enrol in an online course or take help from the internet.
  • Try React - Try online platforms to get a taste of React. You can create a simple HTML page and use React to add some interactivity or you can create a complex React-powered app.
  • Stay informed - Follow the React blog for any updates. Anything important related to deprecation notices or release notes will be first posted here.

React is the need of the hour and the future as it helps the developer in building highly engaging user interfaces and web applications in less time. React’s benefits of being advanced, robust, non-risky, user-friendly, and responsible far exceed its disadvantages. Developers are beginning to understand React’s relevance and are promoting its learning.

React is the one responsible for everything that is happening on the server-side. It mainly influences front-end development.

The main reason why React is faster is because of its virtual DOM that renders everything in JavaScript and changes the things that are changed in actual DOM. Another feature that makes React faster is the keys in Arrays through which React allows fast array changes in elements.

React Native is an entire platform that allows building native, cross-platform mobile applications while React is a JavaScript library used to construct a high performing UI layer.

To choose the best React training institute, you need to look at their course structure. Also, be mindful of the hands-on assignments and supplements. Lastly, check the price. If it's out of your budget, move on to the next option.

Everything was well organized. I would definitely refer their courses to my peers as well. The customer support was very interactive. As a small suggestion to the trainer, it will be better if we have discussions in the end like Q&A sessions.
