Hire How to Employ React JS Developers?

React JS has become an increasingly popular JavaScript framework for front-end development, with an impressive 58.99 million monthly downloads recorded in January of 2022. There are many reasons for this surge in popularity, chief among them being React’s impressive degree of flexibility and scalability. As a result, developers from all backgrounds have been able to take advantage of React’s powerful capabilities to create innovative solutions.

As a consequence, firms all over the globe are embracing React JS technology and employing React JS engineers to make the most of it.

JavaScript is utilised by some of the world’s most prominent corporations such as Uber, Facebook, Amazon, and Twitter for their web-based and mobile applications. The success of these organisations has served as a stimulant, encouraging more businesses to embrace React JS.

The current abundance of React JS engineers has presented an array of challenges when it comes to recruitment. It can be difficult to identify experienced and highly-qualified React JS developers in the job market. Companies must take the time to develop a thorough recruitment process to ensure they are able to secure the most capable and reliable professionals for their React JS development needs.

Here’s a step-by-step process for hiring React JS engineers for your project. But first, let’s go through the basics of React JS.

What exactly is React JS?

Meta and a community of individual developers and corporations manage React JS, a front-end, open-source, and free JavaScript library.

React JS is a declarative and extensible JavaScript framework that can be used to create user interfaces with UI components. It facilitates developers to craft interactive, component-based user experiences. React JS provides an extensive library of tools and features to enable developers to rapidly build reliable, dynamic and engaging user interfaces.

In 2011, Jordan Walke developed and released React JS, which has since seen an extraordinary growth in demand for its development and applications. Since its inception, the popularity of React JS has been steadily increasing and is now widely used across the globe.

What are the benefits of React JS?

React JS is popular due of its several advantages. Here are a few examples:

From a business standpoint –

  • The React JavaScript framework has a virtual Document Object Model (DOM) that includes all of the properties associated with the node tree. The DOM is a method of logically representing the HTML components of a web page or online application.
  • React JS applications do not utilise browsers since they are rendered directly by the server.
  • React JS is a low-cost and SEO-friendly framework.

From the developer’s point of view –

  • The public API of the React JS platform remains intact, making backward compatibility simple.
  • Development teams may use the open-source React JS library to work on new features and address issues.
  • Debugging is simplified by the unique tools provided by React JS, which enable developers to debug their code directly in the browser.
  • React JS is simple to learn and features a concurrent mode for building user-friendly apps rapidly.

React JS developers’ requirements and responsibilities

React JS provides a wide range of opportunities, making it an excellent choice for professionals of all backgrounds and experience levels. In order to determine the precise qualifications for junior, mid-level, and senior React JS engineers, we must look more closely into the specific responsibilities of each. Junior engineers are expected to be able to develop and maintain React JS applications, debug and troubleshoot existing code, and write automated tests. Mid-level engineers typically have a more comprehensive understanding of React JS and its applications, as well as greater experience in debugging, testing, and developing applications. Senior React JS engineers are expected to be able to design, develop, and maintain complex React JS applications, as well as provide technical mentorship to junior and mid-level engineers.

  1. React JS developer at the entry level.

    Junior-level React JS engineers typically possess one to two years of experience in the field, which allows them to understand the fundamental principles of React and Angular. Additionally, they are well-versed in HTML, CSS, Bootstrap, JavaScript, Git, and RxJS.

    Furthermore, junior React JS engineers have intermediate or better written and spoken English skills.
  2. React JS developer with intermediate skills.

    Middle-level ReactJS developers typically possess more than two years of experience with the ReactJS library. They demonstrate a deep understanding of HTML, CSS, BootStrap, JavaScript, Angular, Git and RxJS, and can demonstrate a proficient level of skill when working with Node.

    Middle-level ReactJS developers possess a comprehensive understanding of JavaScript (ES6), TypeScript, and Redux state management. In addition, they typically demonstrate proficiency in developing mobile applications with user interfaces and API endpoints of the highest quality.
  3. React JS senior developer.

    Senior React JS Engineers must possess a minimum of five years’ experience in the field. They should be proficient in utilising React JS and TypeScript to design user interfaces. In addition, they should be well-versed in popular Front-end technologies such as ES6, SASS, WebPack, and Unit Testing.

    Senior React JS engineers demonstrate a high level of expertise and proficiency in a range of programming paradigms, including Model-View-Controller (MVC), Model-View-ViewModel (MVVM), Inversion of Control (IoC), and the design of Representational State Transfer (REST) services/Application Programming Interfaces (APIs). Additionally, they possess a strong command of the English language, typically at an upper-intermediate or advanced level. Furthermore, these experienced professionals are familiar with other popular Javascript frameworks such as jQuery, Vue, and Angular.

Hire React JS engineers from the appropriate sources.

A step-by-step strategy to hiring React JS developers

Step 1: Explain your project, requirements, and budget.

If you are looking to hire React JS engineers, it is important to clearly define your requirements in order to ensure that you and the prospective employee are in agreement. When outlining the necessary skills and qualifications, consider the types of projects that you will be assigning to the engineer and the knowledge, background, and experience that will be required to successfully complete them. Additionally, consider the level of collaboration that is expected and any special certifications or qualifications that may be required. By taking the time to clearly define your expectations, you can ensure that the prospective employee is well-suited to the role.

It is essential to ensure the success of your upcoming partnership by signing a mutually beneficial agreement that covers all the most important aspects. The contract should outline the budget, set deadlines for completion of tasks, and list any sanctions that may be imposed in the event of non-compliance. Doing so will ensure that both parties have a clear understanding of their respective roles and responsibilities.

Step 2: Conduct phone interviews, followed by in-person interviews.

Before hiring React JS engineers for your project, it is important to have a clear understanding of which applicants are the best fit. To ensure the right candidates are chosen, it is recommended to use a resume filtering program to screen applicants. This will help to identify the most qualified candidates for the position.

Once you have obtained the necessary resumes, contact the candidates to commence the telephonic interview phase. When formulating the questions for this stage, take into account their attributes, experience and qualifications.

Step 3: Assess the portfolio in order to employ React JS engineers.

It is crucial to thoroughly assess the projects in which the applicant has been involved to date. Take into consideration their roles, the level of their participation, the outcomes of the projects, and any praise they may have received from their employers. When recruiting React JS engineers, it is essential to conduct a comprehensive evaluation of their profile.

Step 4: Evaluate technical abilities before hiring React JS developers.

The following questions are designed to evaluate the technical proficiency of potential React JS engineers. Utilising these questions will help you determine if the candidate has the necessary technical knowledge to successfully complete the project.

Junior-level questions to ask while hiring React JS devs

Q1. Does React make use of HTML?

A1. React employs JSX, a JavaScript syntax extension that is comparable to HTML.

Q2. What exactly is the CSS box model? How can I reposition boxes on a browser page?

A2. The Cascading Style Sheets (CSS) box model illustrates how the visual formatting model creates rectangular boxes for elements within the document tree. These boxes can be altered in terms of position, margin, and transform through the implementation of CSS.

Q3. How do you name components in React?

A3. If you want the component to be visible, begin with a capital letter. Components that begin with a lowercase letter are treated as DOM tags by React.

Q4: What happens when you use setState()?

A4. The setState() method notifies the component that changes have been made to its state object, and schedules a redraw of the component and its descendants in order to reflect the updated state.

Questions to Ask When Hiring React JS Developers

Q1. What is the technique for converting JSX to JS called?

A1. The process of converting source code from one language to another is known as transpilation. Transpilers are software tools that are used to transform source code written in one programming language into another, often into a language more suitable for the target platform. Popular examples of transpilers include Babel and TypeScript, which are commonly used to convert JSX code to JavaScript.

Q2. What does null signify in Javascript? What is the difference between null and undefined?

A2. The absence of a value associated with an object is indicated by the keyword ‘null’. This term is regularly employed as a placeholder, and when an object reference is no longer necessary (e.g. object = null), it can be removed.

There is a distinct difference between null and undefined. Null refers to when a variable has no value assigned to it, whereas undefined indicates that the variable does not exist.

Q3. Is it feasible in JS to have many inheritances?

A3. Each object in JS is connected with a single prototype. JavaScript cannot inherit from several prototype chains simultaneously.

Q4: What is an event loop in JS?

A4. An event loop is a repeating cycle that monitors the callback queue and the call stack, and is responsible for performing tasks as they arise. In this cycle, the event loop will wait until the call stack is empty before adding the next function from the callback queue onto it. This process is repeated indefinitely, ensuring that tasks are performed in a timely and efficient manner.

Senior-level interview questions for hiring React JS engineers

Q1. What do Higher-Order Components mean?

A1. A higher-order component (HOC) is a function that receives one component as an input and returns another component as an output. This pattern is derived from the compositional nature of React, meaning that components can be composed of other components. HOCs are referred to as “pure” components because they take any dynamically given child component as an input without changing or copying the behaviour of the input component.

HigherOrderComponent(WrappedComponent) const EnhancedComponent

HOC is beneficial in a variety of situations, including the following:

  1. Reusable code, logic, and bootstrap abstraction
  2. Make a hijacking
  3. Abstraction and modification of states
  4. Manipulation of props

Q2. What are the distinctions between a class and a functional component?

A2.

Components of the class:

  • Class-based components make use of the ES6 class syntax. It is capable of using lifecycle approaches.
  • Class Components are an extension of React Components.
  • This keyword must be used to access the properties and functions declared inside the Class Components.

Components that are functional:

  • Functional components are easier to understand than Class-based components.
  • Functional Components are concerned with the application’s user interface rather than its behaviour.
  • These are the displayed functions in the Class Component.
  • Using React Hooks, Functional Components may have a state and simulate lifecycle events.

Q3. What’s the difference between state and props?

A3. Properties (props) and state are both standard JavaScript objects which are used to pass data to components and influence their rendering result. Props are provided to components in the same way that arguments are typically passed to functions, while state is managed internally by the component in the same way that a function might declare its own variables.

Q4. What exactly is prop drilling, and how can it be avoided?

A4. It is common in React applications to utilise a deeply nested component to extract data from a component higher up in the hierarchy. The easiest approach is to pass a property from one component in the hierarchy to the next, from the source component up to the deeply nested component. This technique is known as prop drilling.

The biggest disadvantage of prop drilling is that it makes unknowing components too complex and difficult to maintain.

React Context is a popular strategy for circumventing the tedious process of “prop drilling”. This technique allows developers to create a component that provides data and for its nested components to access this data by means of a consumer component or the useContext hook.

Step 5: Acceptance

It is essential to take into account the perspectives of new employees and ensure they receive the best possible experience to help them become acclimated to the organisation in a timely fashion. To get the process started, here are a few suggestions that may prove valuable:

Steps for Onboarding

  • Send a welcome gift to them.
  • Extend the paperwork and assist them with it.
  • Allow others to use your business tools and applications.
  • Assign a friend to assist them with minor details.
  • Follow these actions to help people understand your corporate culture:
    • Give your employee handbook to them.
    • Display a presentation about the company’s values, purpose, and vision.
    • Display recorded footage of prior all-hands sessions to them.
  • Please inform the candidate of the following:
    • Their first responsibilities
    • Typical working hours
    • Their group
    • Your coding requirements
    • Your anticipations

How much do React JS developers make?

To employ React JS engineers, you must first determine their expected wage range.

The various factors which influence the salary of React developers include the cost of living in their area, their level of seniority, the amount of experience they have, the projects they are involved with, any awards or prominent mentions they have received, and a number of other variables. All of these elements combine to determine the remuneration of React developers.

Studies have revealed that North American wages are generally higher than those in Western Europe. Even within the Western European region, Austria boasts higher wage levels than Spain.

So, how do you go about hiring React JS engineers for your business?
