Logging
The logging feature allows developers to log messages at different levels (info, warn, error) to the console, which is useful for debugging and monitoring the application.

} catch (error) {
console.error(error.message);
}
File System Operations
The file system operations feature provides methods to interact with the file system, such as reading and writing files, which is essential for various CLI tasks.
const { fs } = require('@react-native-community/cli-tools');
fs.readFile('path/to/file.txt', 'utf8').then(data => {
console.log(data);
}).catch(error => {
console.error(error);
});
