Differentiating findFirstChild and square brackets?
I don't completely understand the actual differences when it comes to using findFirstChild and the square brackets, per say:
local part = Instance.new("Part").Parent = game.Workspace
local a = game.Workspace:findFirstChild("Part")
local b = game.Workspace["Part"] -- Using an if statement to check if this exists doesn't work.
local c = game.Workspace.Part
When should I use which?

I like this concept, but I don't know... Rep for the question though. OniiCh_n 410 — 10y

-Use the "." when using a single-word part.
-Use when using a multiple-word part.
-Use FindFirstChild when you aren't sure of the existence of the part or if you want to find a descendant, not just a child.
Example of FindFirstChild for finding descendants:
local model = Instance.new("Model", workspace)
Instance.new("Part", model)
print(Workspace:FindFirstChild("Part", true).Parent.Name) --Prints Model, because of "true" argument.
Example of FindFirstChild if statement:
if Workspace:FindFirstChild("Articulating") and Workspace:FindFirstChild("Torso", true) and Workspace:FindFirstChild("Torso", true).Parent == Workspace:FindFirstChild("Articulating") then
--code
end

I appreciate your explanation of the use of FindFirstChild, thank you! Dummiez 360 — 10y

The FindFirstChild method returns false if it's not able to find the child, while the brackets will throw an error if it's not able to find the child.

local = game.Workspace:FindFIrstChild("Part")
For the top code you are still finding Part.
local b = game.Workspace["Part"]
For the top code you are still finding Part.
