Making a counter for number of spawned enemies killed

[zdrmlpzdrmlp]

it would be easier if you have an Event Bus global AutoLoad to handle the signal
so you wont need to route it from enemy to spawn to counter, something like that
or have to make the enemy reference the counter label

How do I connect signals via code in Godot 4.2?

when a child sending a signal to a parent (since using get_parent() is a bad practice from what i read) or when a node needed to broadcast a signal to whole node about something, it will come useful notice that the signal is a built-in signal made for Area2d node, you also can create a custom signal depending on what you need Also, take a look at Global EventBus for simpler signaling: https://gdscript.com/solutions/signals-godot/#:~:text=the%20script%20file.-,Global%20Event%20Bus,-In%20GoDot%…

with the EventBus Autoload:
it would be like
event_bus.gd

signal dead

enemy.gd

EventBus.emit_signal("dead")

counter.gd

func _ready():
	EventBus.dead.connect(counterplus)

see how it skipped the mob spawn script and just straight connect to where it needs via the event bus
