TypeScript for Beginners - RegEx Program 1

The video tutorial explains how to validate a cell phone number to ensure it has at least 10 digits. It guides through creating a file for validation, defining a string for the cell number, and using a regular expression to enforce the 10-digit rule. The tutorial demonstrates how to apply the regular expression to a string and check its validity using a method that returns true or false. It also covers testing the validation by modifying the number and observing the results in a web browser console.
