Core Concepts to Master
Components and Props
In React Native, components are reusable pieces of code that represent UI elements, such as buttons, text inputs, and images. Props (short for properties) are used to pass data from a parent component to a child component, allowing for seamless communication between components.
State and Props
State is an object that stores data that can change over time, such as user input or API responses. Props, on the other hand, are immutable and used to pass data from a parent component to a child component. Understanding the difference between state and props is crucial for building efficient and scalable React Native applications.
React Navigation
React Navigation is a popular library for building navigation in React Native applications. It provides a simple and intuitive API for creating navigation flows, handling navigation events, and managing navigation state.
