How to use the @hpcc-js/comms.Version function in @hpcc-js/comms

function test(build: string, prefix: string, major: number, minor: number, patch: number, postfix: string): boolean {
    const version = new Version(build);
    return version.prefix === prefix && version.major === major && version.minor === minor && version.patch === patch && version.postfix === postfix;
}
