FWIW, could be also done by moving it out from the template string to a separate param:

console.warn(`failed to query /capabilites/qemu/migration on '${target}':`, err);

If it exists this is always an array per the schema though,
so the following might be enough:

if (typeof comigratedHAResources === 'array') {

Or use the ExtJS frameworks' Ext.isIterable() while under the hood it's a bit more
heuristic than your check, it should cover all (for us) relevant cases

if (Ext.isIterable(comigratedHAResources)) {

Your variant might be fine as Proxmox.Utils method though, but rather overkill for
now.
