The faker npm package is a powerful tool for generating massive amounts of fake data in Node.js and the browser. It is commonly used for testing, bootstrapping databases, and creating realistic-looking UI prototypes. Faker can generate data for various categories, including names, addresses, phone numbers, dates, and more.

Generates a random full name. Useful for creating user profiles or contact lists in testing environments.
faker.name.findName();Generating Addresses

faker.address.streetAddress();Generating Internet-related Information
