While going through the JavaScript Algorithms and Data Structures Certification curriculum I had to write various functions. So, I decided to take this challenge a bit further and implement a UI for it and dive more into testing.

A palindrome is a word or sentence that's spelled the same way both forward and backward, ignoring punctuation, case, and spacing (e.g. mom, dad, racecar, madam). A palindrome checker checks if a string is a palindrome or not.

Mobile number validation is the process of checking if a mobile number is accurate. It lets you find out if the mobile number you have for a business contact is active and able to receive calls or not.

The Caesar Cipher technique is one of the earliest and simplest method of encryption technique. It’s simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example, if the Cipher was a ROT1 (rotate by 1 letter), then every a in the message would show up as a b. I have made a ROT13 cipher, it will encrypt your messages by rotating the letters by 13 characters.

Roman numerals are a number system developed in ancient Rome where letters represent numbers. The modern use of Roman numerals involves the letters I, V, X, L, C, D, and M. I made a converter which can convert numbers from 1 to 3999 into Roman numerals or viceversa.

The point of this project is to have each key, when pressed, make a corresponding drum noise. It also uses CSS transitions and animations to make the project more interactive to the user.
