Level 39 (Challenge): Build addSignature

Now let’s add a function that adds a signature to a message.

Function signature:

addSignature(message, from) → string

Examples:

• addSignature('Happy Birthday, Alex!', 'Sam') → "Happy Birthday, Alex! — from Sam"
• addSignature('Happy New Year, Sam!', 'Alex') → "Happy New Year, Sam! — from Alex"

Your task:

1. Write tests for addSignature first
2. Implement the function
3. Test with different messages and signatures

Try it: Add tests and the function to your greeting.test.js and greeting.js files!
