: Instead of just numbers, use unique characters like # , & , or even multi-character strings like [X] .

Create Your Own Encoding: A Step-by-Step Guide for CodeHS 8.3.8

: Your code must look at every single letter in a word. You’ll use a for loop that starts at index 0 and runs until the end of the string ( str.length ).

The objective of this assignment is to create a program that translates a standard string (English) into a secret code (encoded) based on a set of rules you define.

: Ensure your encodeLetter function has a final else statement that returns the original character. If you don't, any letter you didn't write a rule for will show up as undefined .

: Double-check your for loop syntax: (let i = 0; i < str.length; i++) .

Cracking the code for is a milestone for many intro programming students. It’s the moment where you move beyond just following instructions and start thinking like a cryptographer.

To build a robust encoding program, your code generally follows this flow:

: You start with an empty string ( let encoded = ""; ). Every time your loop finds a new encoded letter, you add it to that string. A Common Example Structure

In computer science, this is known as . You take an input, look up its corresponding value in your "key," and output the result. The Logic Breakdown
