Sending SMS Messages with Deno, TypeScript, and Twilio Messaging

Sending SMS messages programmatically enables reaching many people almost simultaneously. With Twilio Messaging, creating a Deno application can send many messages and report when each has been delivered or not. The tutorial project creates a helper library that sends an SMS message to a phone number and reports its status. The library is built with Deno in mind and uses the Twilio Messaging SMS service. It defines an interface for the SMS request, a class to handle the request, and methods to send the message and poll its status. The tutorial also covers setting up a Twilio account, registering a phone number, and using environment variables to store sensitive information like API keys.
