Number.MAX_SAFE_INTEGER — adding 1 loses precision

📖 Usage Example

// Largest safely representable integer
Number.MAX_SAFE_INTEGER   // → 9007199254740991
Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2   // → true (unsafe!)

Use Number.MAX_SAFE_INTEGER as the upper bound when working with integers to avoid silent precision loss.

Precision Loss Beyond MAX_SAFE_INTEGER

Adding 1 to Number.MAX_SAFE_INTEGER produces an incorrect result due to precision loss.

Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2  // → true!

💡 Hints (1)

• Beyond `MAX_SAFE_INTEGER`, integers can no longer be represented exactly.
