React js development

FAQ

• Virtual Dom. Why it is faster?

  React's Virtual DOM is mainly a js Object that’s why it is faster than real Dom. Thanks to reading/writing on an object it is not costly. So when any changes (events, objects) were sent to virtual DOM it simply changes on the real DOM.

• React js. Is this library or a framework?

  The library differs from the framework by the notion that the framework describes the architecture and configuration of the developer code. Therefore, how your application should be developed depends entirely on this. Imagine that it’s like a frame for the house. At the same time, the library is more appropriate for a piece of furniture and interior filling, which, in turn, we add into the already made house.

  React js really offers some key features. You decide how to handle the library, however, it is still rather ambiguous as to how certain actions should be performed (GraphQL requirements, Flux, etc.). Despite all this, Facebook introduces React js as a library.

• What languages React js supports?

  As already mentioned, this technology is a Javascript library, therefore it is made on the basis of Javascript. To use it, js developers mostly use Javascript. If desired, they can use JSX or Javascript addition, XML-Esque to construct user interface modules. The JSX syntax will be transformed to its Javascript corresponding, but basically, it is much easier to be written.

  React is a very widespread technology, that’s why there are bindings for practically all languages that are ported to JavaScript (Flow, ReasonML, ClojureScript, TypeScript, etc.). Developers can find a huge number of various documents on how to bound it with appropriate languages (for instance, ReactJS.NET, which makes it better usage in apps based on C#).

• Does it require any extra setup?

  To configure React js, it is not enough to simply run the installation file. Its configuration requires many processes. Beginning from React js library installation, other packages that need to be set, and finishing with many configurations to create a comprehensive React js development environment.

  There also need to install useful packages such as webpack and babel, forming them to create a full React js development environment. Perhaps you may skip the installation of these packages and still build simple projects deprived of them, but dealing with bigger projects, their installation is required.

• Could the React js library be added to an actual project?

  Yes, this technology can be connected to live projects because of being a library. To start, developers need to set up it on their system, which means that they just need to integrate react and react-dom script into the current HTML code of any project, and then request the Javascript file having the component that they created, also using a tag of the script. In the end, the div tag is positioned through the name of the component as its identifier, where the React js component should have been placed, and no more actions needed.

• What about the gradual migration in React js?

  React was specifically created to facilitate gradual adaptation. After all, it is possible to use only certain functions, missing all the others. Later, developers can incorporate more React js functions into their codebase. Well-known companies such as Netlify have switched from other JavaScript libraries towards React js, performing this step by step.

• React’s competitors. What are they?

  Angular was the only competitor since the React js creation. Currently, you can find more than 10 presented libraries and frameworks that also spread on the field of React js functioning. Vue is the most well-known of them, but such solutions as Ember, Aurelia, Elm, Mithril are also in high demand.
