The library comprises re-usable components. React Developers can create with them an entire page or use only chosen ones. Projects of this type are fast, scalable, and relatively easy to build.
React quickly became very popular with developers. Currently, it is the most used solution … type of application (surpassing the popularity of Angular and Vue.js).
React is used for various types of projects. It is a solution that streamlines code creation, which you will appreciate when creating applications such as the type of:
React will work well when building an extensive application for sending live messages. It is used, for example, by Slack, Discord, Messenger or Skype. React Developers can create both a mobile and web application.
Instagram and Facebook are good examples of using React to create dynamic social media applications. They have good performance and can handle all the functions needed by users, such as uploading videos and photos, displaying notifications or publishing posts, adding likes and many more.
Amazon, Etsy and Walmart built e-commerce applications using React.js due to, i.a., the speed of its operation. Their solutions have an efficient user interface. You can see it when displaying products, doing the search or carrying out the purchase process.
React is used by companies such as Spotify, SoundCloud, or Netflix. This most popular video streaming service needed an application that could handle a large amount of dynamic content. The company chose React for its speed of launch and operation or its modular structure.
An example of an educational application built with React is Khan Academy. Its creators appreciated, above all, the quality of the code that was created using the library.
From a developer's point of view, the advantages of React.js are:
React’s components generate the HTML snippet. These are unique objects that can also be used in other projects. Even a complicated application is divided into many independent “bricks”, which makes it much easier to create.
DOM is a single object that represents the entire HTML document. React uses a virtual DOM that is more efficient and leads to create a better user interface. It also speeds up the work of programmers.
If a programmer changes a child component, the parent component is not affected. This gives React engineers greater control over the code of even complex applications. This also makes it easier to correct bugs when they are detected during testing. All of these saves developers’ time.
The disadvantages of React
React is a library, not a complete all-in-one framework. To create a complete application, developers also need to use other tools (such as based on React.js React Native).
React uses JSX syntax, although it is not required for application development. Some programmers find it too complex and difficult to learn. At the same time, it has many advantages, which is why React programmers are eager to use it.
React is is being developed rapidly, which can be both a pro and con of it. The advantage is that programmers can benefit from regular improvements that can raise the quality of the project. The downside is they need to keep up with quick modifications, which takes time to learn.
Because of the fast pace of development, the documentation may miss information about the latest changes. In addition, resources of varying quality can be found online because they are created by the user community.
When deciding to hire a React-developer, pay attention to whether he knows the following technologies:
These are the basic programming languages for websites. Knowing them is essential for every front-end web developer. He should also have experience in RWD (Responsive Web Design).
JSX is the basic syntax used in React. To master it, React engineer need to be fluent in HTML.
When hiring a React Developer, pay attention primarily to his portfolio. He should have experience with this type of project, preferably of any kind. In addition, he must be up-to-date with the changes that occur in the technologies he needs to work. React is updated frequently, and the developer has to be interested in its evolution.
