Error Management
This feature provides utilities for managing and formatting errors that occur during interactions with the Ethereum blockchain.

// Some code that might throw an error
} catch (error) {
const formattedError = errors.ErrorResponse(error);
console.error(formattedError);
}
Data Formatting
This feature includes functions for formatting data, such as converting between different units of Ethereum (e.g., from Wei to Ether).
const { formatters } = require('web3-core-helpers');
const weiValue = '1000000000000000000';
const etherValue = formatters.fromWei(weiValue, 'ether');
console.log(etherValue); // Outputs: 1
Utility Functions
This feature provides various utility functions, such as checking if a string is a valid Ethereum address.
const { utils } = require('web3-core-helpers');
const isAddress = utils.isAddress('0x742d35Cc6634C0532925a3b844Bc454e4438f44e');
console.log(isAddress); // Outputs: true
