Don't know about Node modules (maybe whatever JOSE module you use has
such function?), but:
function is_signature_alg(alg)
{
return /^[EPR]S(256|384|512)|EdDSA$/.test(alg);
}
function is_mac_alg(alg)
{
return /^HS(256|384|512)$/.test(alg)
}
(Those two do direct regexps with known valid JOSE signature and MAC
algorithms).
