  1. Start on paper. Write down your custom mapping for at least 10 characters. For example: ‘a’=1, ‘b’=2, ‘c’=4 (skip 3), etc. Ensure every character maps to a unique number.
  2. Build the encoder first. Write a function that takes a string and returns a list of integers based on your paper mapping. Test it on a short word like “cab.”
  3. Build a reverse dictionary. From your mapping, create a second dictionary where keys are the numbers and values are the characters.
  4. Write the decoder. Use the reverse dictionary to convert a list of numbers back into a string.
  5. Test symmetry. Encode a phrase, then decode the result. Do you get the original phrase? If not, debug systematically.
  6. Add characters incrementally. Start with lowercase letters, then spaces, then uppercase, then punctuation. Test after each addition.
  7. Handle errors. What happens if a number in the decode list does not exist in your reverse dictionary? Your code should probably raise a meaningful error or return a placeholder.
  8. Optimize (optional). If your encoding produces very large numbers, consider modulo or subtract a base value.

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