How does validator.normalizeEmail work?

validator.normalizeEmail is a function in the validator library that normalizes an email address by converting it to lowercase and removing extra whitespace. When you call validator.normalizeEmail(), you pass in an email address as a parameter. The function then performs the following steps to normalize the email address: Convert the email address to lowercase: validator.normalizeEmail() converts all characters in the email address to lowercase to ensure consistency. Remove extra whitespace: validator.normalizeEmail() removes any extra whitespace characters (e.g., spaces, tabs) from the beginning and end of the email address, as well as any whitespace characters between the local part and the domain part of the email address. Remove dots from the local part of the email address: validator.normalizeEmail() removes any dots (.) from the local part of the email address, since dots do not affect the routing of the email message. Remove tags from the local part of the email address: validator.normalizeEmail() removes any tags (e.g., +label) from the local part of the email address, since they are not part of the actual address. validator.normalizeEmail() then returns the normalized email address as a string. This function is useful for tasks that require validating and normalizing email addresses in JavaScript, such as in web forms or user registration systems. Overall, validator.normalizeEmail provides a simple way to normalize email addresses in JavaScript using the validator library.

const validator = require("validator");

// Normalize an email address
const email = "   John.Doe+Label@example.com  ";
const normalizedEmail = validator.normalizeEmail(email);

// Log the original and normalized email addresses to the console
console.log(`Original email: ${email}`);
console.log(`Normalized email: ${normalizedEmail}`);

In this example, we use validator.normalizeEmail to normalize the email address 'John.Doe+Label@example.com'. We pass in the email address as a parameter to validator.normalizeEmail(). The function then normalizes the email address by converting it to lowercase, removing extra whitespace characters, and removing any dots or tags from the local part of the email address. It returns the normalized email address as a string. We then log both the original email address email and the normalized email address normalizedEmail to the console. Overall, validator.normalizeEmail provides a simple way to normalize email addresses in JavaScript using the validator library.
