Mobile applications have become essential to communication, shopping, banking, education, entertainment, healthcare, logistics, and business operations.

Organizations need mobile experiences that are fast, interactive, intuitive, and accessible across different devices.

However, creating separate applications for Android and iOS can require different programming languages, tools, and development teams.

React Native offers another approach.

It allows developers to use JavaScript and React concepts to create cross-platform applications that can operate on Android and iOS devices.

The Developing Mobile Apps with React Native program provides a structured learning path from JavaScript fundamentals to complete mobile application development.

Across five connected courses, learners study JavaScript, React, React Native, Expo, Redux, APIs, databases, notifications, publishing, interface design, GitHub, and mobile app marketing.

You may also be able to Start Learning Free by opening one of the individual courses and checking whether a Preview or audit option is available.

What Is React Native?

React Native is an application framework used to create mobile apps with JavaScript and React.

Instead of maintaining completely separate frontend codebases for Android and iOS, developers can reuse a significant amount of application logic and interface code.

React Native applications use native mobile components, allowing developers to build mobile experiences that interact with platform features while benefiting from React’s component-based development model.

React Native can be used to create:

• Business applications
• E-commerce apps
• Educational platforms
• Social applications
• Booking systems
• News apps
• Financial tools
• Productivity applications
• Health and fitness apps
• Customer-service solutions
• Internal company tools
• Data-driven mobile products

The framework is particularly valuable for developers who already understand JavaScript or React and want to expand into mobile development.

Why Learn React Native?

Cross-platform development can reduce duplicated work and make it easier to create consistent experiences across mobile operating systems.

Learning React Native can help developers:

• Build applications for Android and iOS
• Use JavaScript for mobile development

JavaScript Fundamentals

Learners explore essential programming concepts, including:

• Variables
• Values
• Data types
• Operators
• Functions
• Events
• Arrays
• Objects
• Reference types
• Program logic
• Error handling

These foundations help learners understand how applications process instructions and respond to different conditions.

ECMAScript 6

ECMAScript 6 introduced several features commonly used in modern JavaScript development.

These may include:

• Arrow functions
• Template literals
• Classes
• Modules
• Destructuring

Error and Exception Handling

Applications need to respond appropriately when unexpected conditions occur.

Learners explore techniques for:

• Identifying errors
• Handling exceptions
• Debugging code
• Preventing application failures
• Communicating problems clearly

DOM Manipulation

The Document Object Model represents the structure of a web page.

Although React Native does not use the browser DOM in the same way as a website, DOM exercises help learners understand dynamic interfaces and event-driven programming before moving into React.

Learners practice:

• Finding page elements
• Changing content
• Updating styles
• Traversing page structures
• Responding to events

AJAX and APIs

AJAX allows applications to request information without refreshing an entire page.

• Dashboard section

Component-based development can make an application easier to understand, maintain, test, and expand.

JSX

JSX allows developers to describe interface structures within JavaScript-based React components.

It combines familiar markup concepts with application logic.

React Components

Learners create reusable components that can receive information and display different content.

Reusable components can reduce duplicated code and support consistent application design.

Props

Props allow information to pass from one component to another.

They help developers configure reusable components without rewriting them.

State

State represents information that may change while an application is running.

Examples include:

• Form input
• Shopping-cart contents
• Selected items
• Search results
• User preferences
• Loading states

When state changes, React can update the relevant parts of the interface.

React Hooks

Hooks allow functional components to manage state and perform other application operations.

Learners explore how hooks can support modern React development.

Forms and Event Handling

Interactive applications must respond when users:

• Click buttons
• Enter information
• Submit forms
• Select options
• Add products
• Remove items

Learners create interfaces that respond to these events.

Redux

Redux supports structured state management across larger applications.

It can help when multiple components need access to the same application information.

Practical React Applications

Learners demonstrate their skills through frontend projects, including a shopping-cart application.

These projects provide experience with:

• Reusable components
