    };

    if (version.includes('+')) [version, metadata.buildInfo] = version.split('+');

    if (version.includes('-')) [version, metadata.preRelease] = version.split('-');

    const parseVersion = (ver) => ver.split('.').map(num => isNaN(Number(num)) ? null : Number(num));

    if (version.startsWith('^')) {
        metadata.range = '^';

        version = version.slice(2);
    }

    [metadata.major, metadata.minor, metadata.patch] = parseVersion(version);

    return metadata;
}
