JS Practice — Built-in Objects

String.prototype.toString() — in template literal

📖 Usage Example

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

Use toString() to return the primitive string value of a string or String object.

String.prototype.toString() — Template Literal

When you embed a value in a template literal, JavaScript calls .toString() implicitly.

Challenge: Implement wrapInGreeting(name) that returns 'Hello, <name>!'.

wrapInGreeting('World') // → 'Hello, World!'
