JS Practice — Built-in Objects

valueOf() — comparison with primitive

📖 Usage Example

// Retrieve the primitive numeric value
const n = new Number(42)
n.valueOf()          // → 42
typeof n.valueOf()   // → 'number'

Use valueOf() on a Number object to extract the underlying primitive number value, which JavaScript also calls automatically in numeric expressions.

valueOf() and Comparison

A Number object loosely equals its primitive value because == calls valueOf().

💡 Hints (1)

• Loose equality (`==`) triggers `valueOf()` on objects; strict equality (`===`) does not.
