Number.MIN_SAFE_INTEGER — isSafeInteger at boundary

📖 Usage Example

// Most negative safely representable integer
Number.MIN_SAFE_INTEGER   // → -9007199254740991
Number.MIN_SAFE_INTEGER - 1 === Number.MIN_SAFE_INTEGER - 2   // → true (unsafe!)

Use Number.MIN_SAFE_INTEGER as the lower bound when working with negative integers to avoid silent precision loss.

isSafeInteger at MIN_SAFE_INTEGER Boundary

Test Number.isSafeInteger at and around MIN_SAFE_INTEGER.

💡 Hints (1)

• Safe integers span from `MIN_SAFE_INTEGER` to `MAX_SAFE_INTEGER` inclusive.
