I'm using TypeScript and creating some AWS listeners. I want two different ports 443 and 22. I need a clean way to create these without duplicating the new construct. The port property only takes an single string and not an array. Any ideas?

can you share your code?

If you're just trying to be DRY, something like this may work. If I have resources with mostly identical config, but differences in ports/sg/etc... I'll create loops like this to avoid recreating the resource over and over.

const listenerPorts = [22, 443];
const albListerners: aws.lb.Listener[] = [];

for (
  const range = { value: 0 };
  range.value < listenerPorts.length;
  range.value++
) {
  albListerners.push(
    new aws.lb.Listener(`listener-${range.value}`, {
      loadBalancerArn: pulumi.output(alb).arn,
      port: listenerPorts[range.value],
      protocol: "HTTPS",
      sslPolicy: "ELBSecurityPolicy-TLS-1-2-2017-01",
      certificateArn: pulumi.output(acmCert).arn,
      defaultActions: [
        {
          targetGroupArn: pulumi.output(albTargetGroup).arn,
          type: "forward",
        },
      ],
    })
  );
}

That looks interesting, thanks @shy-waiter-84958. Yes, trying to keep it DRY.
