Number() — converting booleans

📖 Usage Example

// Convert a value to a number
Number('42')    // → 42
Number(true)    // → 1
Number(false)   // → 0
Number('')      // → 0

Use the Number() function to explicitly convert a value to a numeric type, which is more predictable than implicit coercion.

Number() — Boolean Coercion

Number(true) returns 1, Number(false) returns 0.

Challenge: Implement boolToNum(b) that converts a boolean to a number.
