CodeHS exercise 8.3.8 requires 5 bits per character to represent 27 unique symbols (A–Z and space), as 4 bits are insufficient for the necessary 27 combinations. The process involves creating a unique binary mapping for each character and applying it to encode a target phrase, such as "HELLO WORLD". For a detailed breakdown, visit Course Hero.
for (var i = 0; i < text.length; i++)
var char = text[i];
if (encodingMap[char] !== undefined)
output += encodingMap[char];
else
output += "?????";
Create a Decoding Scheme: For every encoding scheme, there must be a decoding scheme. This is usually the reverse of the encoding scheme. 83 8 create your own encoding codehs answers

Mastering CodeHS 8.3.8: Create Your Own Encoding – Answers and Deep Dive
If you are navigating the CodeHS JavaScript curriculum, specifically the "Basic Data Structures" or "Cryptography" section, you have likely encountered the exercise 8.3.8: Create Your Own Encoding.
🎍 The Goal
The objective is to write a function called encoder that takes a string and returns a new "encoded" string. You can choose any encoding scheme you like, as long as you follow the rules:
Part 2: Create the Decoder
We need to reverse the dictionary to look up letters based on binary strings.
my_decoder = {}
for key, value in my_encoding.items():
my_decoder[value] = key
