Heartbeat and While Loop Practically Identical?

Help and Feedback Scripting Support
#1

I apologize if this is a redundant post as this question doesn’t have major importance, but I wanted extra clarification on the matter.

On pretty much every post that I see asking for the difference between RunService Heartbeat and While Loops, I always see the same response that they are different because while loops are slower.

This should be inherently false, because task.wait() is the same as waiting on heartbeat:

while true do
		task.wait() -- same as one heartbeat - Right?
		print("New Frame")
	end
	-- In theory are identical
	game["Run Service"].Heartbeat:Connect(function()
		print("New Frame")
	end)

I’m looking for somebody to confirm whether that’s true or false.

Now the one advantage that heartbeat serves regardless if it’s inherently the same as while loops, is delta time, because it allows you to equalize stuff with different frame rates etc:

while true do
		timeSpent += 1 -- Will update faster on higher frame rates
		task.wait()
	end
	
	game["Run Service"].Heartbeat:Connect(function(dt)
		timeSpent += dt -- Will update at the same rate on all frame rates
	end)

HeartBeat depends on the Physics’s FPS, to get the Physics FPS you can do this in a script

workspace:GetRealPhysicsFPS()

Most of the time it returns 60, similiar to Frame Per Second, you can divide 1 By the Returned number to see how Fast the Physics updates in seconds and how Long will a HeartBeat:Wait() take
