Convert String Array to String

📖 Usage Example

const words = ['hello', 'world']
words.toString()  // → 'hello,world'

Use toString() for a quick comma-joined string when a simple representation is enough.

Array.prototype.toString — String Arrays

toString works on arrays of any type, not just numbers. It joins all elements with commas.

Implement stringArrayToString which returns the comma-separated string representation of a string array.
