  • Functions and arrow functions
  • DOM Manipulation and event handler
  • The “this” keyword
  • The “class” keyword
  • Prototype chain and object creation
  • Higher order functions and callback functions

Well conversant with JS build tools

Excellent understanding of testing frameworks and tools

Rising quick-deployment needs during the development phase, testing has become an  important skill for React developers. Therefore, the React developers should know about Jest, Enzyme, Mocha, Chai, AVA, and Tape for unit testing. For end-to-end testing, the React developers must know about Selenium, Webdriver, Cucumber.js, Nightwatch.js, Cypress, and Puppeteer. For integration testing, React developers must know about Karma.

Experienced in working with Version Control System (VCS)

React Native developers must have a very good knowledge of version control systems, like Git, SVN, TFS, and Mercurial. Mostly, React Native developers use Git for their work. It is the version control system that helps the team in collaborating and organizing your code, maintain the frequent changes that occur in the code. Git helps in reviewing the old codes and compares them with the newly updated code, pulling the code from their repository, and managing the commit history.

Along with this, the developer must know how to use add, push, pull, and commit commands, branching, and merging as it allows developers to work independently on the code.

Knowledge of MVC architecture

React Native developers must know about Model-View-Controller (MVC) architecture. MVC approach helps you to create applications that separate the input logic, business logic, and UI logic while maintaining the loose coupling between the elements. Model is responsible for implementing business logic and handles the data that is passed between a user interface and a database. Controller acts as an intermediate between model and view and controls the way a user interacts with an application. When a user requests some data, it is the controller that determines what response should be sent to the user.

Strong grasping on ReactJS UI library framework

As React Native is built on the top of ReactJS, which is one of the most demanding skills today for developing smooth-running and interactive UIs with its two powerful tools -JSX and DOM Manipulation. The React Native developers must know about the React UI components React Router, Material UI, Bootstrap, Semantic UI, and webpack. Check their knowledge of JSX, Virtual DOM, and Props.

Experience with web markup and UI, UX Concepts

The React Native developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The React Native App developer must be experienced in developing visual effects in presentational markup. For, example – How the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells. 

Experience working with ReactJS workflows

Very important point : State management in React.js is the biggest challenge developers face while dealing with the large applications. Look for the React Native developers developers who have worked with state management in their projects where they have managed states across multiple components and optimized application performance. Check if they have worked with the popular libraries like Redux, Mobx, and REST and Context APIs.

This open-source JavaScript framework provides smooth-running interactive UIs by implementing ReactJS UI library thereby increasing the user experience quality. A dedicated React. Native developer is responsible for developing native mobile applications with React reusable components. But recruiting the top talented React.Native developers is not an easy task when a large no. of React Native programmers are competing to grab the job opportunities.

Top Interview Questions to ask while hiring a React Native developer

React Native is a Javascript framework designed for building native mobile applications because of its code sharing advantage on both Android and iOS devices while React.js is a Javacript UI library framework which gives the developer advantage of JSX (Javascript Syntax Extension) and Virtual DOM creation. React Native uses React UI components to build interactive and smooth running UIs.

Here are some of the core differences - 

  • ReactJS and React Native both uses JSX but React Native doesn't use HTML tags while ReactJS uses.
  • For Navigation, ReactJS uses React Router while React Native uses its own navigation library.
  • For animations, React Native uses animated APIs while ReactJS uses CSS animations.
  • For DOM, React Native uses its built-in native APIs while rendering the components, while React.js uses virtual DOM.
  • React Native is designed for developing mobile applications while React.js is used for web application development.

JSX stands for JSX stands for Javascript XML. This is a type of syntax extension which allows us to directly write HTML in React by converting HTML into React components, which helps you to easily create user interfaces for your web applications.

The virtual DOM is a programming concept where a virtual representation of UI is kept in memory and synced with the real DOM with the help of a library like ReactDOM. This process is called "Reconciliation".

Whenever any data is changed in UI, the changes are rendered in Virtual DOM first, then Virtual DOM is compared with Real DOM, the Real DOM will be updated only with the things that have been changed.

State is a type of data used by the mutable components and can change their value at any time. The developer initialize the state in the constructor and then invoke the setState function to change its value.

The lifecycle of the component consists of four phases -

  • Initialization - The constructor() method is called before anything else when the component is initiated and sets up the initial state and other initial values. This method is called when your component is created but is not added to the DOM. Its main use is to initialize the state and bind this for component methods.
  • Mounting - The component is added to the React DOM. Mounting includes the following methods like constructor(), getDerivedStateFromProps(), render(), and componentDidMount().
  • Updating - The component receives changed props or states and is called when the components is re-rendered. Updating the component includes shouldComponentUpdate (), componentWillUpdate (), componentDidUpdate () methods.
  • Unmounting - The component is removed from the React DOM. It includes the method componentWillUnmount().

After invoking the setState() function, the passed object is merged into the current state of the React component. This process triggers Reconciliation. Reconciliation updates the UI in a most efficient manner. React Native constructs a tree of React elements and compares it with the previously designed element tree. This enables React Native to make updates in the necessary places.

Props stand for Properties in React. Props are the read-only components generally used to render dynamically generated data. Props are passed in the functions as similar as the arguments are passed. Props are always sent from parent to child component and never vice-versa.

  • Props are immutable while the States are mutable.
  • Props allow you to pass information from one component to another in the argument form, while a State doesn't pass but holds the information about the components.
  • Props make a component reusable by passing it to the child component while States do not have any functionality like this.
  • Props are external and are controlled by whatever renders the component while the State is internal and is controlled by the React Component itself.
  • Props are used to communicate between the components, States can be used for rendering dynamic changes with the component.

Following are the core components of React Native - 

  • View - A view is a container that provides layout with flexbox like accessibility controls and touch handling.
  • Text - A text nests text strings, displays styles, and manages touch events.
  • Image - Image component is responsible for showing different kinds of images to the user.
  • ScrollView - ScrollView is a  scrolling container responsible for containing multiple rows and columns.
  • TextInput - Users enter the text with TextInput.
