RangeError: Exponent must be positive (V8-based)RangeError: BigInt negative exponent (Firefox)RangeError: Negative exponent is not allowed (Safari)

RangeError.

The exponent of anexponentiation operation must be positive. Since negative exponents would take the reciprocal of the base, the result will be between -1 and 1 in almost all cases, which gets rounded to0n. To catch mistakes, negative exponents are not allowed. Check if the exponent is non-negative before doing exponentiation.

const a = 1n;const b = -1n;const c = a ** b;// RangeError: BigInt negative exponent

Instead, check if the exponent is negative first, and either issue an error with a better message, or fallback to a different value, like0n orundefined.

const a = 1n;const b = -1n;const quotient = b >= 0n ? a ** b : 0n;
