Now, while browsing the comments, you will see that the count of likes has increased by 100 whenever you liked the image without even reloading the page. This magic count change is due to Reactjs.React is a definitive, prolific and versatile JavaScript library for building UIs.

 It is ‘V’ in MVC. ReactJS is a component-based open source front-end library, responsible only for the application preview layer. It is maintained by Facebook.

React uses a declarative paradigm that facilitates thinking about its application and aims to be efficient and flexible. Create simple views for each state of your application and React updates efficiently and represents the correct component when the data changes. The declarative display makes your code more predictable and easier to debug.

ReactJS is an open source JavaScript library that is used to create user interfaces specifically for single page applications. It is used to handle the preview layer of web and mobile applications. React also allows us to create reusable user interface components. React was created by Jordan Walke, a software engineer who works on Facebook. React was first implemented in Facebook news in 2011 and in 2012.

Learning Outcomes of our Best React js Training

ReactJS advantages

  1. Easy domain. React is based on lightweight programming languages, enough to remember how HTML works and voila, you're in business. It is not necessary to study TypeScript deeply, as in Angular, sufficient superficial knowledge.
  2. High level of flexibility and maximum responsiveness.
  3. The Document Object Model (DOM) allows you to combine HTML, XHTML or XML documents according to certain criteria, usually in a tree, so React is ideal for web browsers when analyzing various elements of web applications.
  4. It is excellent when working with ReactJS ES6 / 7 and can handle any load.
  5. Linking data with each other (in a certain direction, often down) ensures the immutability of the primary data; Child elements cannot change the data string.
  6. An open source JavaScript data library is improved daily, thanks to open source, developers around the world are making technological contributions to the database.
  7. The lightweight database, processes that occur by the user, can easily participate in the server.
  8. Migration between versions is usually very simple, Facebook provides "code codes" to automate a large part of the process.

React JS, a JavaScript library particularly suitable for designing user interfaces in extensive data-driven web applications, allows updates and rendering of components without reloading the page. Basically, the main winning stars of React JS on GitHub are the ability to simplify the creation of interactive user interfaces and also the comfortable coexistence with other libraries or JavaScript frameworks such as AngularJS. Not only is it maintained by Facebook, but also used by commercial giants such as PayPal, Uber, Airbnb, Netflix and BBC. Therefore, it is unlikely that its uninterrupted popularity and established position in the community will lead the ranking next year.

React contains the complete collection of integrated tools or clichés that the software development engineer gets used to. Status management at the component level. The new React connection context and API means that you do not need a third-party library and can manage functional states at the component level, improving modularity and reuse

The difference is that for the first one, the components come with all the necessary dependencies and themes injected for you. This means that the CSS of each dependency will be available in its final CSS automatically. In contrast, with raw components, CSS is not included.

Now the main question before us is why I should use ReactJS. There are many open source platforms to facilitate the development of front-end web applications such as Angular. Let’s take a quick look at the benefits of React over other competitive structures or technologies. With the front world changing daily, it is difficult to take the time to learn a new structure, especially when that structure can finally become a dead end. So if you are looking for the best option, but you feel a bit lost in the jungle of frameworks, I suggest you check React.

Here are the five most impressive features of React.js chosen by the Placement point solutions team.

  1. Simply put, the concept is “say what, not how.” You can create the application’s user interface by creating view after view. With React.js, the code focuses on what is shown, not on the steps to be followed. For a noncoder, the second approach seems more intuitive. And it is actually faster to create and debug a screen or component with this method. Declarativity means excellent DX (developer experience), which generally translates into an excellent UX.


  1. Component based approach. You can create applications with React.js using building blocks: components that may be responsible for a user interface function (for example, a button), network communication (for example, a data browser) or very long functions. more complex, such as managing the state (for example, Redux Provider). This modular approach facilitates the implementation and visualization of a design system (for example, with Storybook). The components in React.js are an attractive DX.


  1. Minimalism. React.js is small and fast to download. It doesn’t take much work to set up the programming environment. In addition, you do not always have to load the entire application thanks to the code division function, which can significantly reduce the loading time of your site or web application. Fast and easy loading times are crucial for both the user experience and the marketing (SEO) of your product, because Google promotes sites with short load times.
  2. Huge ecosystem and flexibility. When choosing a technology for your digital product, you want to use a programming language or framework that is already popular, and most importantly, that will remain popular in the future. Extensive use provides the most crucial features: a set of talented developers who know about technology and want to learn and excel in it, and expand component libraries and new application areas. React.js has it all.


  1. Compatibility with previous versions. It is always good that the software can work with previous versions of the libraries it uses (or depends on). However, few languages   and frameworks can provide backward compatibility because it is expensive. Fortunately, Facebook had to invest in maintaining compatibility with previous versions for internal corporate use. Some FB applications still execute code snippets created when React was still in its infancy, with no compatibility issues.

Real DOM                                                          

  1. Updates slowly.
  2. You can directly update the HTML.
  3. Create a new DOM if the item is updated.
  4. DOM manipulation is very expensive.
  5. A lot of memory waste.


  1. It updates faster.
  2. You cannot update HTML directly.
  3. Update JSX if the item is updated.
  4. DOM manipulation is very easy.
  5. No memory loss.
  • React is a front-end JavaScript library produced through Facebook during 2011.
  • Follow the component-based approach, which helps build reusable user interface components.
  • It is used for the development of complex and interactive web and mobile interfaces.
  • Although it was open source only in 2015, it has one of the largest communities that support it.

The main features of React are listed below:

  1. Use the virtual DOM instead of the real DOM.
  2. ii) Use the server side representatio
  3. iii) Follow the unidirectional data stream or data link.
  • Some of the main advantages of React are:

    1. increases application performance
    2. ii) It can be conveniently used on client and server.

          iii) Due to JSX, the readability of the code increases

    1. React is easy to integrate with other structures such as Meteor, Angular, etc.
    2. With React, writing UI test cases becomes extremely easy.

The reaction limitations are listed below:

  1. Reacting is just a library, not a complete structure
  2. ii) Your library is very large and requires time to understand

            iii) It can be a bit difficult for beginner programmers to understand

           iv. Coding becomes complex as it uses online modeling and JSX 

    • JSX is an abbreviation for XML XML. This is a type of file used by React that uses JavaScript expressivity along with HTML syntax as a template. That makes the HTML file certainly simple to follow. This file makes applications robust and increases its performance.

A virtual DOM is a lightweight JavaScript object that was originally only the copy of the real DOM. This is a node tree which lists every elements, their attributes including content being Objects and their properties. The React rendering function creates a node tree from the React components. Then update this tree in response to mutations in the data model caused by various actions taken by the user or the system.

This virtual DOM works in three simple steps.

  1. Each time you change any underlying data, the entire UI will be represented again in the virtual DOM representation.
  2. Then, the difference between the previous representation of the DOM and the new one is calculated.
  3. At the end of the calculations, the actual DOM will be updated only with the things that really changed.
