[ 🐣 Weekly Tip - Don't use anonymous functions to connect events! ]

:mailbox_with_mail: [June - 1st week tip]

When connecting events like Touched to multiple objects in a loop, use a named function instead of an unnamed one. (anonymous)

:x: Example with unnamed functions (not recommended):

local RootFolder = workspace:WaitForChild("Parts")

for _, part in ipairs(RootFolder:GetChildren()) do
    if part:IsA("BasePart") then
        part.Touched:Connect(function(otherPart)
            local character = otherPart.Parent
            if character and character:FindFirstChild("Humanoid") then
                print("Player touched the part:", otherPart.Name)
            end
        end)
    end
end

Using an anonymous function inside a loop creates a new closure for every iteration.
Closures can capture external variables and hold references that the Garbage Collector (GC) might not release properly, which can drive to memory leaks over time.`

:+1: Better approach using named functions:

local RootFolder = workspace:WaitForChild("Parts")

local function OnPartTouched(otherPart)
    local character = otherPart.Parent
    if character and character:FindFirstChild("Humanoid") then
        print("Player touched the part:", otherPart.Name)
    end
end

for _, part in ipairs(RootFolder:GetChildren()) do
    if part:IsA("BasePart") then
        part.Touched:Connect(OnPartTouched)
    end
end
