how to handle Error in React Native – errorhandling

There are several ways to handle errors thrown in React native program, here are some common approaches but these are not limited :

• Try-catch blocks: You can use a try-catch block to wrap code that might throw an error, and handle the error in the catch block. For example:

try {
  // code that might throw an error
} catch (error) {
  console.error(error);
}

const fetchData = async () => {
  try {
    const response = await fetch('https://example.com/data');
    const data = await response.json();
    return data;
  } catch (error) {
    console.error(error);
  }
};

import { ErrorUtils } from 'react-native';

const globalErrorHandler = (error, isFatal) => {
  console.error(error, isFatal);
  // display fallback UI or send the error to an error reporting service
};

ErrorUtils.setGlobalHandler(globalErrorHandler);

Be mindful of some approaches as they may be more appropriate for different types of errors or contexts. It’s a good idea to choose the error handling approach that best fits your needs.
