How to build international phone number input in HTML and JavaScript

This project utilizes the intl-tel-input plugin to create an international phone number input field that processes and parses phone numbers using basic HTML, JavaScript, and the plugin's configuration options. The plugin provides a country code dropdown with flags to represent different countries, normalizes user input to include spaces, parentheses, dashes, and more, and formats the phone number in E.164 format as required by many APIs. The project also includes recommendations for phone verification and fraud prevention, such as normalizing phone numbers in E.164 format and performing a phone verification using Twilio's Verify API.
