React.JS Coding Test
In fast-scaling tech companies, React developers are a competitive asset to scale up their operations. While there is a consistently high demand for React developers, it is quite difficult to find the ones who actually deliver. Most candidates who list react on their resumes have variable skill sets with some might just have the surface knowledge. However, with the growing expectations in front-end roles, a good React developer should be able to deliver clean, production-ready, scalable applications. This skill gap is a major roadblock for recruiters. The challenge is far beyond just scanning candidates' resumes. They need a keen eye to sort candidates based on their real-world skills and that’s where the React online test comes in. Testfuse React assessments are carefully designed to objectively evaluate candidates’ understanding of React and their real-world coding skills. These skill assessments let recruiters filter out the potential candidates from the ones who just have a surface-level understanding of React. Testfuse React coding test is a smart scalable solution that makes the hiring process efficient and unbiased. It helps to find best-in-class developers who deliver sustainable software solutions.

React.JS Coding Test
What is React?
Description
React, commonly known as React.js or ReactJS, is a popular Javascript library developed by Jordan Walker in 2013 for Facebook (now known as Meta). It is a front-end Javascript library and is widely used in web development for building UI components. It is an open-source library that empowers front-end developers to develop interactive and dynamic web and mobile pages. It has a component-based architecture that makes it efficient for developing maintainable and easy-to-test code. It is a go-to choice across industries because of its high-performance reusable components and flexibility to integrate it with other frameworks and libraries. Also, it fulfills the requirements of website and mobile developers making it a widely chosen JS library. Some of the industries that rely on React for developing applications include the software industry, Fintech, e-commerce, healthcare, real estate, logistics, etc. React developers rely on the React Java Script library to develop UI components that are user-friendly, responsive, and efficient. These developers write clean codes for an improved user experience. However, it can be difficult to assess the skill set and expertise of React developers. Skill-based assessments are a perfect solution to evaluate the theoretical familiarity and practical knowledge of the candidate.

Key Areas in the React.JS Screening Test
If you are hiring a React.JS developer, it is important to question their understanding of basic to complex concepts. These concepts are important for junior, mid-senior, and senior-level resources. Testfuse screening test includes questions from the following key areas that are a must-learn for any skilled React.JS developer.
Components
JSX
Props
Virtual DOM
Hooks
State
Component Cycle
Error Handling
Test Tools
Components
Understanding React.JS components is a must-have concept for any professional. These code blocks are fundamental for any user interface. These individual blocks have their logic and ensure code modularity.

JSX
For efficient development, React.JS experts use JavaScript XML which lets them write HTML-like code in Javascript. Though not necessary it makes it easier to work with React.JS to elaborate what UI will look like.
Props
Another core concept is the understanding of props. Just like the functions in JS, these props are a way of communication between React.JS components. Parent components use props to send information to the child component.
Virtual DOM
Virtual DOM is the lightweight, memory-based representation of the actual DOM ((Document Object Model). This virtual DOM is created for changes in React.JS and later the algorithm compares two DOMs and merges minimal changes into actual DOM to boost speed and efficiency.
Hooks
Hooks are the functions in React.JS that allow developers to use its functions without actually writing a class. Knowledge and proficiency in using existing hooks (useState, useEffect, useContext, and useReducer) or creating custom hooks is a must-have for developers.
State
Understanding of state built-in React.JS objects enables developers to create dynamic UIs. The use of state and proficiency in dealing with changing states over time is crucial for developing responsive applications.
Component Cycle
A core concept in React.JS development is the understanding of all three phases of a component cycle. It helps the developers ensure a smooth user experience, boost performance and tackle performance issues.
Error Handling
Error handling in React.JS is important for any developer to prevent unwanted code crashes that affect the performance. Efficiency in using error handling components and functions such as error boundaries and error handlers is crucial for any developer.
Test Tools
Another must-have skill for any React.JS developer is familiarity and proficiency with testing and debugging tools such as Jest, Enzyme, and RTL (React.JS Testing Library) to prevent mistakes.
