Decoder ring project that I did through Thinkful

Project Decoder Ring

A JavaScript project with 3 different functions that a user can use to encode and decode messages.

Features

Caesar Shift

When the user enters a string of letters, the letters will shift to either the left or right of the alphabet. The user enters a string of letters, a number to shift, and whether or not to shift forwards or backward.

Polybius Square

When the user enters a string of letters, a string of numbers is returned, or vice versa. Each letter is set to a specific number shown in the Polybius square.

Substitution cypher

Users can either encode or decode a message, using a substitute alphabet. The user enters 3 inputs. The first is a message, the second a substitute alphabet, and finally whether to encode or decode the message.

Technology

Built with vanilla JavaScript, including:

• Higher-order functions
• Regular expressions
• Destructuring

Discoveries

Figured out what a regular expression is, and used it to complete my goals. Got better acquainted with destructuring and higher-order functions.

Future Goals

Refactor the code to make it more concise and use more techniques that I have learned since completing the project.
