String.prototype.valueOf() — returns primitive string

📖 Usage Example

const str = 'Hello'
str.valueOf()               // → 'Hello'
new String('hi').valueOf()   // → 'hi'

Use valueOf() to return the primitive string value, useful when working with String wrapper objects.

String.prototype.valueOf()

str.valueOf() returns the primitive string value of a String object or primitive.

Challenge: Implement getValueOf(str) that calls .valueOf() and returns the result.

getValueOf('hello') // → 'hello'
