83 8 Create Your Own Encoding Codehs Answers [updated] Guide

Before writing the code, it is vital to understand what encoding actually means. Computers cannot directly store letters, symbols, or emojis. They only understand binary numbers (0s and 1s).

At its heart, an encoding is a system of rules. It’s a dictionary that defines how to represent a piece of data as something else. In computer science, we most often talk about —how text characters (graphemes) are translated into the binary (1s and 0s) that computers can process. The most common standard is ASCII, where, for example, the letter 'A' is represented as the decimal number 65, which in binary is '01000001' .

To complete this assignment, you must master three fundamental programming concepts.

If your code is not passing the automated CodeHS grading test cases, check for these common pitfalls: Before writing the code, it is vital to

To explain exactly what is happening in the code blocks above, let's trace a single word through the encoding pipeline using a shift value of 4 . Example Trace: Encoding the word "CAT" : charCodeAt / ord returns 67 . Add the shift: fromCharCode / chr turns 71 into 'G' . Character 'A' : charCodeAt / ord returns 65 . Add the shift: fromCharCode / chr turns 69 into 'E' . Character 'T' : charCodeAt / ord returns 84 . Add the shift: fromCharCode / chr turns 88 into 'X' . The final output printed to the screen will be "GEX" . Common Mistakes to Avoid

// In case of trailing incomplete codes, they are ignored. return decoded; At its heart, an encoding is a system of rules

: Ensure your loop visits every index from 0 to length - 1 .
