TFNFR13 - Default Values with coalesce/try

The following example shows how "${var.subnet_name}-nsg" SHOULD be used when var.new_network_security_group_name is null or ""

Good examples:

coalesce(var.new_network_security_group_name, "${var.subnet_name}-nsg")

try(coalesce(var.new_network_security_group.name, "${var.subnet_name}-nsg"), "${var.subnet_name}-nsg")

Bad examples:

var.new_network_security_group_name == null ? "${var.subnet_name}-nsg" : var.new_network_security_group_name)
