Hire ReactJS Developers

React is a JavaScript library with a component-based structure. It is different from other frontend frameworks as it uses a virtual DOM or Document Object Model to optimise updates to the actual UI of a web page. So, React applications are faster. The framework also uses a declarative approach to create UI, which is unlike other frameworks.

Virtual DOM, the interface that allows browsers to understand the style of a web page, JavaScript Syntax Extension, and component-based architecture are the main features of React. Also, the framework follows unidirectional data flow and extends its efficiencies to mobile app development through React Native.

JSX allows me to combine HTML and JavaScript in coding and converting HTML tags to elements in React. JSX prevents the need for using createElement() and appendChild() methods while placing HTML elements in the DOM.

State is a JavaScript object in React. It keeps data that I can use to influence the rendering of a particular component. The State is like a piece of information that can be switched over time. It influences the way a component appears or responds to user inputs or any other event.

I was intrigued by how ReactJS allowed Facebook to run several user interfaces, such as news feed updates and chat, at once. This made me delve into it further, and I realised React’s significance in building scalable and high-performing web apps. I chose to specialise in React to enhance my skills as a developer and build highly compatible apps.

I ensure that my React applications respond quickly to user interactions with techniques like windowing, fine-tuning list rendering and memoising extensive computations. I also use various performance optimisation tools to find dependencies and optimise them.

I regard feedback as an opportunity to improve my understanding of using React and deliver superior final results. Also, I thoroughly understand the suggestions and ask questions whenever I feel that a particular recommendation is not actionable.

I am experienced in working closely with stakeholders, web designers, and project managers to create strong React applications. To ensure good collaboration, I ask for feedback and use shared project management tools. I also make sure that I am aware of the joint goals of all the teams.

One of the most challenging React projects I worked on was about building a complex web application. It had an extensive codebase and needed integration with many third-party services. Besides, the application demanded a highly responsive user interface.

I used React with Redux, Typescript and Node.JS to create the code and used techniques like windowing, memoization and throttling to improve performance. I kept asking and acting on feedback to ensure successful development. Also, I set realistic goals to complete different parts of the app and continuously tested them for increased reliability.

I test React components, Redux actions and asynchronous code through unit testing with Jest. For enhancing accessibility and verifying the DOM structure, I use the React Testing Library for integration testing. In addition, I use DevTools to debug my applications.

I follow the feed of influential React developers on X and have subscribed to newsletters like This Week In React, Bytes and React Status. Also, I read the articles on React on Medium to learn about new developments.

Writing the perfect code and meeting a deadline is not a practice that I encourage. When I faced this situation in the past, I changed my entire schedule and started working earlier than usual to complete the code by the deadline.

Adding CSS inline styles to React components, component-based styling, and React responsive design are some of the common styling approaches. I also use themes in my React app for better visual consistency and identity.

I ensure web accessibility using React through HTML practices like using Casing and Reserved Words. Also, to ensure that the title element does not show the same content throughout the browser session, I use React’s lifecycle method- componentDidMount(). Additionally, I use automated static analysis and browser tools to discover accessibility problems.

HOCs are functions that take a component as an argument and give back a new component. This new component wraps up the original one. A Higher Order Component is used to add more functionality to a component without changing its code.

The Context API is perfect for less complex, minor state management when you are only required to share data between a few components. However, Redux is more appropriate for more extensive apps with a more intricate state management system, thanks to features like Redux Thunk for handling async operations.

For client-side routing, I use React Router. It enables me to set up the routes and navigate between the different components without the need for a whole page reload. For dynamic routing, I always use useParams to handle path parameters.

In functional components, I use hooks like useEffect for side effects, which replicate lifecycle methods such as componentDidMount, componentDidUpdate, and componentWillUnmount. It helps me handle the side effects such as APIs, events, and cleanup more effectively.

Dynamic import() as well as React’s React.lazy() helps me to split code and only load the components that are needed in the current view, which enhances the start time of the app. It is effective for complex applications that possess many components and routes in them.

For cases like data fetching or API calls, I often utilize useEffect in functional components. For more complicated cases, I use Redux Thunk or Redux Saga middleware to manage async operations in a more efficient and maintainable manner.

Higher-order components interact with a component to produce a new component for replicating logic between components. I have applied HOCs in integrating authentication measures and in improving components that have more data-fetching power.

I use controlled components to manage the form state. For complex forms I prefer to use Formik or React Hook Form to handle validations, dynamic fields, and states, this makes the process easier and more effective.

React Fiber is an effective reconciliation framework in React specially designed for enhanced rendering efficiency. It fragments rendering work into small sequential tasks, which allow React to pause and continue working with a task, enhancing the responsiveness of the app, including the most complicated UI.

PropTypes in ReactJS are used for checking the type of props that are being passed into a component, this prevents incorrect types from being used in the development process. With the ability to warn against incorrect prop types, PropTypes improve code quality and reducibility of errors, allowing for bugs to be caught early on in the development process.

In most of my applications, I employ Firebase Authentication or Auth0 for handling authentication and keeping user tokens in the local storage or cookies. For authorization, I use the react-router to protect the routes that are only accessible by authenticated users.
