: Double-check your for loop syntax: (let i = 0; i < str.length; i++) .
: 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 . 83 8 create your own encoding codehs answers exclusive
function start() let phrase = readLine("Enter a phrase: "); let secretMessage = encode(phrase); println(secretMessage); function encode(str) let result = ""; for (let i = 0; i < str.length; i++) let letter = str.charAt(i); result += encodeLetter(letter); return result; function encodeLetter(char) char == 'S') return "$"; else // Return the character as-is if no rule exists return char; Use code with caution. Tips for "Exclusive" Customization : Double-check your for loop syntax: (let i
To build a robust encoding program, your code generally follows this flow: Every time your loop finds a new encoded
: 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
By following this structure, you aren't just copy-pasting an answer; you're building a functional piece of software that demonstrates a core concept of data security and string manipulation.
