What is an enterprise ReactJS developer?

React is a JavaScript library/framework created by Jordan Walke, a Facebook engineer, in 2011. It is designed to make writing large web apps easier by making it possible to encapsulate code and markup into components, which you can use elsewhere. It has become very popular, with over 42% of web developers having used it due to its power and relatively low learning curve.

React pioneered the use of a virtual DOM, which allowed for writing your web app declaratively without suffering a significant performance loss. With traditional web applications, you explicitly define how the HTML DOM should be updated whenever data changes. However, with React, you only need to define how data is used in markup, and whenever that data is updated, the markup updates with it.

This design is great for simpler code but can lead to performance issues, as React does not know what markup will change and therefore has to update and re-render everything. To solve this, React introduces a virtual DOM, a piece of data React keeps to track the differences before and after a state change and only update what markup actually changes. The virtual DOM was what allowed for a lot of React’s quality-of-life features, and was one of the main reasons behind its popularity.

How to hire ReactJS developers FAQ

ReactJS hiring guide

A React developer needs to have a good understanding of JavaScript, HTML, and at least one declarative web UI framework. The UI framework is preferably React, but as long as you know one, learning React is not too hard. They should also know how to develop scalable, modular frontends, as that is a core part of React.

For each experience level, different levels of knowledge and skills are expected when hiring a React developer:

  • An entry-level React developer should understand JavaScript and HTML well, and have experience with a declarative web UI framework, whether it is React, Vue, Svelte, or some other framework. They should have some understanding of how to develop a component-based frontend using composition. These developers might only work on individual components and smaller areas, which in combination with other developers, can make up something bigger.
  • An intermediate JavaScript developer should have a lot of experience with React, HTML, and JavaScript. They should fully understand how to write idiomatic React code and be able to “think in React.” They should also understand some more advanced React features, like Portals and Context. These developers can create larger components like complete pages and should be able to help other developers troubleshoot.
  • A senior JavaScript developer has a significant amount of experience using React and should have created many React websites. It is expected that they understand advanced features like Portals and keep up with the newest React features. They can lead larger teams in building out features and should be able to provide their technical experience and perspective to help influence the direction of the product.

ReactJS interview questions

Question 1: How would you create a button counter in React?

This question is React-specific and helps test for basic state management. Most solutions should be something like this:

There can be variability in these answers, so the best thing to do is to run it yourself and make sure the counters function properly.

Question 2: How would you load data from an API on the first load of a page using React?

This is a good test of how the interviewee understands component mounting, initial page rendering, and how to use useEffect() with side effects.

In this example, the component fetches data from a REST API when it is first rendered. The useEffect hook is used to initiate the fetch and update the component state with the response data. The second argument to useEffect is an empty array, which tells React to only run this effect once when the component is first mounted.

Question 3: How would you create a simple login form in React?

This question is intentionally more flexible than other questions. Here you can see how interviewees structure their HTML/JSX and React code. Here is an example of a correct answer:

Once again, there are a variety of solutions to this. A good solution would get the job done using React features well, but the best solutions are ones that use semantic form elements and are designed to work with and without JavaScript (like the one above).

Question 4: How can React.memo() optimize React component rendering?

This question helps show a more in-depth knowledge of React and performance optimization. The correct answer should be that React.memo() checks whether the props of a component have changed before re-rendering it, meaning that if the parent component is re-rendered frequently and the child component’s props do not change as much, the rendering work React has to do will be reduced.

Beware of answers that say you should never or always use it. It has a specific use case and placing its usefulness on one extreme or the other shows a lack of knowledge of advanced React optimization.

Question 5: What are React portals for?

Portals are rather advanced, so this helps to see how much advanced React the interviewee knows (this is unrelated to performance optimization, unlike the previous question). The correct answer is that portals allow React components to render child components outside of the parent component. Another good thing an interviewee might add is that React portals should only be used when necessary, as they can lead to bad practices.

What is the two-week guarantee for Torc ReactJS developers?

The best way to evaluate whether a developer is a great match is by working with them. That's why we make it as easy as possible to get started.

It's a no-risk way for you to get the help you need even faster.

How does Torc ensure high-quality ReactJS candidates?

How much do Torc ReactJS developers cost?

Developers in the Torc community set their own rates. The three primary factors that determine the cost of a Remix developer are:

  1. Experience - Everyone would prefer a senior developer but, let's be honest, 10+ years of experience isn't always required. If you consider the work the developer will be doing and the amount of support within your existing team they'll have access to, you might be better served with one or two junior Remix developers over one senior developer.
  2. Skill mix - Marketplaces operate under normal supply and demand dynamics. Developer rates often increase with more niche, complex, or in-demand skill requirements.
  3. Geography - While remote work has flattened the geographic pay disparity to some degree, where your developer lives does factor into their cost. In 2022, the median rate for Torc developers in Latin America was 29% lower than developers in the U.S., Canada, and Western Europe, while the median rates in Eastern Europe and Asia/Oceania were 24% and 40% lower, respectively.
