Project Details
JavaScript implementation of an algorithm that validates US telephone numbers.
Regular expressions are awesome.
They were certainly useful for this project, anyway. Using regular expressions in conjunction with the str member function search , I managed to design a solution to the telephone number problem in just a handful of lines!
The CodePen link above will open an in-browser code editor and console. Tinkering at the console will enable you to interface with the telephoneCheck function I implemented. Below are some of my personal friends' and family members' phone numbers to try for testing:
