Number.MAX_VALUE — isFinite check

📖 Usage Example

// Largest finite positive number
Number.MAX_VALUE        // → 1.7976931348623157e+308
Number.MAX_VALUE * 2    // → Infinity

Use Number.MAX_VALUE to check against the largest representable floating-point value before performing operations that could overflow to Infinity.

isFinite Check on MAX_VALUE

Number.MAX_VALUE is finite even though it is enormous.

💡 Hints (1)

• `MAX_VALUE` is finite — only `Infinity`, `-Infinity`, and `NaN` fail `isFinite`.
