Interview with Dedicated React JS Developers
Here at Mobilunity we try to follow the trends, and to always know what are the popular technologies on the market. As a Dedicated Teams provider, we get a lot of requests for a remote React.js developer for hire, so of course, we made our own research on why is the technology the biggest trend in Front-end development today. Our React Developers Denis and Roman, working on a French marketplace project, gladly helped us to figure out why React and what trends in React web development currently exist. See our video interview and read the transcript below.
The host of our mini interview with React engineers is Olga, Account Manager at Mobilunity, who will be happy to answer all your questions about hiring remote react developer and building remote dedicated teams.
Why ReactJS is so popular right now?
Denis: Everyone is excited about so-called React Fiber, which is an ongoing reimplementation of React’s core algorithm. It will increase suitability of React for things like animation, allowing to split components rendering into multiple chunks, prioritizing some of them and having the ability to pause or even abort rendering of less important parts of application. This big change will define the future of React for the next few years and as most of React developers, I`m looking forward to trying it in a real application.
Roman: I think React is so popular because it simple to learn, understand and easy to use, has good and big community and also brings some new approaches into creating client side applications.
For what kind of projects is React.JS a good solution?
Denis: React is a fantastic solution for interactive data-driven apps. In the end, the need to create such apps was the initial reason for creating this library. It is also worth looking at for large teams, because it helps to create clear, expressive, self-documenting code that is easy to extend and integrate.
Roman: React should be a good solution for reach client side applications with different components and actions, React allows to separate interface parts into complete independent reusable components.
Directly from your own experience – how does it differ from any other JS framework?
Denis: From my own experience, it`s less permissive, compared to other libraries and tools out there. It really helps the developer to watch himself by throwing exceptions and warnings on certain actions, falling outside of React paradigm.
Roman: First of all React is just a library, so it differs from all JS frameworks, because each of them has own rules and approaches in building applications, React just allows you to create cool interfaces but not build whole application structure.
What are pros and cons of using this framework?
- Nice performance thanks to Virtual DOM and possibility to optimize components by making them “pure” ( only rely on data from component’s props or state for rendering UI, ignoring global variables ).
- Minimalistic API, that is really easy to get familiar with, and clear mental model of component’s lifecycle.
- React is a small performant view library, that makes no assumptions about the rest of project’s technology stack. So instead of monolithic approach taken by AngularJS, for example, where you have everything ( e.g. templating, routing, data fetching ) packed together out of the box, you are free to decide what you want to use. You can attach React components to virtually any application architecture, as the only principle it enforces is component-based approach, that fits well in most of existing application development patterns.
- The need to use additional transpiling and bundling tools like Babel or WebPack, that require extensive configuration to adjust to one’s specific needs.
- It`s really easy to start creating React components, but it takes some time of trial and error to learn to make them really clear, slim and composable. If you start a new project with little knowledge and experience in React, your codebase can quickly become a bloated mess with extremely low level of code reuse. The good news is, thanks to certain level of isolation between React components, refactoring it will be much less of a pain than with most of other front-end libraries and frameworks.
- The point mentioned in ‘pros’ – that React being a small view library has little effect on overall application design – can also be viewed as a con. The great benefit of monolithic frameworks is that most of the time you know where some part of your future app should go. With React it’s not so obvious – you should decide by yourself how and where you want to make requests to your server-side, where to store your data and whether to separate application data from UI state. It`s quite easy to take a wrong path while making all of these decisions, especially for inexperienced developers.
- Clear and rich core library
- Component system approach
- Good performance
- It is just a library, so it requires additional tools for building reach and complete web apps.

Why do you like ReactJS?
Denis: There is a lot of things I like about React. What I would like to highlight is great encapsulation offered by React components. If you choose a right set of input data for the component, you can change it`s implementation completely without the need to make any changes to views that use this component. I also like clear and obvious data flow through components. Accidental and unwanted data mutations are very rare thanks to certain restrictions enforced by React – like you can’t change component’s props from the inside of component and you can only mutate component`s state through ‘setState’ method. These clear rules make developers threat the data with caution and in a uniform way, which is great while working and using React for big projects.
Roman: Mostly I like it for it’s simple principles and good performance.
How do you think this framework will change in a next few years?
Denis: Everyone is excited about so-called React Fiber, which is an ongoing reimplementation of React’s core algorithm. It will increase suitability of React for things like animation, allowing to split components rendering into multiple chunks, prioritizing some of them and having the ability to pause or even abort rendering of less important parts of application. This big change will define the future of React for the next few years and as most of React developers I’m looking forward to trying it in a real application.
Roman: I guess it will be supported by community and creators.
Of course, this is not everything that we can tell about React.JS! Each and every React developer at Mobilunity is very talented and extraordinary, so feel free to send more questions to our team or submit the required job description. We will be ready to find the answers and source the perfectly matching developers for you.
