How To Check If An Object Exists Correctly?
Quick question! Right now I'm using an if statement:
if game.Workspace.part ~= nil then
-- Do something
end
If the part doesn't exist, then I'm getting an error because it is looking for the part to check if it is nil. It works in the sense that the code inside won't run unless the part does exist, but I'd rather have fully functional and optimized code.
So that leads me to my question- what should I be using instead?

do this if you want a child with a specific name:
if workspace:FindFirstChild("Part") then -- use workspace, game.Workspace is deprecated
end
if you want to find a child that is a part then do this
if workspace:FindFirstChildOfClass("Part") then
end
if you want all the children that are for example a tool or a part then do this:
for i,v in pairs(workspace:GetChildren()) do
if v:IsA("Part") then
-- use v instead of part now
end
end

Um, where does it say game.Workspace is deprecated? It’s the other way around. User#19524 175 — 6y

You could:
if workspace:FindFirstChild('part') then
print('part exists')
end
-- Or
if not workspace:FindFirstChild('Part') then
print("part doesn't exist :c")
end
Hopefully, this helped, best of luck developer!
Edit: Fixed the string
