The parseInt function will return NaN for invalid version parts, which could lead to incorrect comparisons. Consider adding validation to ensure all parts are valid integers before proceeding with the comparison.

Suggested change

	// Parse version strings into arrays of integers
	const v1Parts = version1.split('.').map((part) => parseInt(part, 10));
	const v2Parts = version2.split('.').map((part) => parseInt(part, 10));
	// Helper to parse and validate version string
	function parseVersionParts(version) {
	const parts = version.split('.');
	return parts.map((part, idx) => {
	// Only allow non-empty strings of digits
	if (!/^\d+$/.test(part)) {
	throw new Error(`Invalid version part '${part}' at position ${idx} in version string '${version}'`);
	}
	return parseInt(part, 10);
	});
	}
	const v1Parts = parseVersionParts(version1);
	const v2Parts = parseVersionParts(version2);

The function doesn't validate input parameters. Consider adding checks for null/undefined version strings and ensuring the operator is a valid string to prevent runtime errors.
