Why ReactJS Is More in Demand

One of the most in demand technologies right now is #ReactJS

  • As stated already, the most compelling feature of React is that it reduces the complexities of user interface.
  • If the mechanism that we are trying to interface can comprehend Javascript, we can use React to build the user interface for it.
  • You describe the user interfaces in React languages and tell it what you want, it will take care to translate your description and prepare the actual interface.
  • You will illustrate user interfaces to React with simple components.
  • When state of a component changes, its User Interface will change automatically.

ReactJS is a JavaScript library for building user interfaces. According to Google Trends data last 5 years in increased popularity of ReactJS development and we explain why ReactJS is more in demand.

React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.

Vue vs React: Battle of the Javascript Frameworks

#Vue vs #React: Battle of the #Javascript Frameworks 
#VueJS #reactjs

  • I’ve created two nearly identical sample applications, one in Vue and one in React, if you’d like to give either framework a shot in the context of the samples in this article.
  • The biggest difference is that React popularized a Virtual DOM (we’ll get into this later) and created a new syntax called JSX that allows developers to write HTML in JavaScript.
  • Unlike earlier JavaScript frameworks that had ‘batteries included,’ both React and Vue are fairly barebones with functionality like routing and state management handled by separate frameworks.
  • Both React and Vue are focused solely on the UI layer, and leave functionality such as routing and state handling to companion frameworks.
  • In Vue there’s no need to call a state management function like , as the data parameter on the Vue object acts as the holder for application data.

The one thing that no one properly explains about React — Why Virtual DOM

The one thing that no one properly explains about #ReactJS — Why Virtual DOM?

  • By relinquishing DOM manipulation for itself, it allows for different components or pieces of your code to request DOM modifications without having to interact among themselves, without having to go around sharing the fact that they’ve modified or want to modify the DOM.
  • The particular behaviour can be achieved without a virtual DOM. You can manually group all the DOM modifications in a DOM fragment yourself and then dump it into the DOM.
  • virtual-dom will then figure out how to make the DOM look like this efficiently without recreating all of the DOM nodes.
  • The style information along with the nodes in the DOM tree are used to create another tree, called the render tree
  • All nodes in the DOM tree have an “attach” method, which takes in the calculated style information, and returns a render object (a.k.a. renderer)

@ReactiveConf: “The one thing that no one properly explains about #ReactJS — Why Virtual DOM?”


The other day a friend had this React question for me: “Composition through components, one way data binding; I understand all that, but why Virtual DOM?”..
