Help with macros and functions

[dimejo]

I hope someone can help me to create a reusable function for HTTPS entries. My HTTPS entries consist of 3 DNS records (A, AAAA and HTTPS). The plain code looks like this:

D("example.com", REG_NONE,
  A("alpha", "192.168.1.1"),
  AAAA("alpha", "2001:0DB8::1"),
  HTTPS("alpha", 1, ".", "alpn=h3,h2 ipv4hint=192.168.1.1 ipv6hint=2001:0DB8::1"),
  A("beta", "192.168.1.2"),
  AAAA("beta", "2001:0DB8::2"),
  HTTPS("beta", 1, ".", "alpn=h3,h2 ipv4hint=192.168.1.2 ipv6hint=2001:0DB8::2"),
  A("gamma", "192.168.1.2"),
  AAAA("gamma", "2001:0DB8::2"),
  HTTPS("gamma", 1, ".", "alpn=h3,h2 ipv4hint=192.168.1.2 ipv6hint=2001:0DB8::2"),
);

What I came up with to make this easier to read and maintain:

var HOST1_A = "192.168.1.1"
var HOST1_AAAA = "2001:0DB8::1"
var HOST2_A = "192.168.1.2"
var HOST2_AAAA = "2001:0DB8::2"

function FUN_HTTPS(name, ipv4, ipv6) {
  A(name, ipv4),
  AAAA(name, ipv6),
  HTTPS(name, 1, ".", "alpn=h3,h2 ipv4hint=" + ipv4 + " ipv6hint=" + ipv6),
}

D("example.com", REG_NONE,
  FUN_HTTPS("alpha", HOST1_A, HOST1_AAAA),
  FUN_HTTPS("beta", HOST2_A, HOST2_AAAA),
  FUN_HTTPS("gamma", HOST2_A, HOST2_AAAA),
);

This doesn't work, but as I don't know any javascript I have no clue why. Is what I'm trying to do even possible?

@dimejo you're on the right track! See the working code example below:

var HOST1_A = "192.168.1.1"
var HOST1_AAAA = "2001:0DB8::1"
var HOST2_A = "192.168.1.2"
var HOST2_AAAA = "2001:0DB8::2"

var FUN_HTTPS = function(name, ipv4, ipv6) {
    return [
        A(name, ipv4),
        AAAA(name, ipv6),
        HTTPS(name, 1, '.', 'alpn=h3,h2 ipv4hint=' + ipv4 + ' ipv6hint=' + ipv6),
    ];
};

D("example.com", REG_NONE,
  FUN_HTTPS("alpha", HOST1_A, HOST1_AAAA),
  FUN_HTTPS("beta", HOST2_A, HOST2_AAAA),
  FUN_HTTPS("gamma", HOST2_A, HOST2_AAAA),
);

Thank you, that worked!
