function Jovan.New(className : string) : (props : any) -> GuiObject
	return function(props : any) : GuiObject
		local newUI = Instance.new(className)
		local cssProps = {}
		for name, val in pairs(props) do
			if markers[name] then continue end
			newUI[name] = val
		end

		if props[CHILDREN_MARKER] then
			for _, element in ipairs(props[CHILDREN_MARKER]) do
				element.Parent = newUI
			end
		end

		if props[DECLARATION_MARKER] then
			for name, val in pairs(cssProps) do
				Properties[name](newUI, val)
			end
		end
		return newUI
	end
end

local New = Jovan.New

local root = New "ScreenGui" {
	Parent = workspace,
	[Jovan.Children] = {
		New "TextLabel" {
			Text = "Works",
			Size = UDim2.fromOffset(100, 200),
		},
	},
	[Jovan.Declarations] = {
		centered = true,
	},
}

Could anyone tell me why the [Jovan.Declarations] and [Jovan.Children] are expected to be the same type? I’ve tried changing the function definition’s types but that wont do anything

#2

{any} means an array of any value, basically {[number]: any}, I think you’re looking for something like {[string]: any}

#3

I never defined {any} anywhere its the linter assuming the type of it when it shouldn’t be

#5

I’ve been reading through the documentation on strict type checking recently, but it doesn’t say anything about performance. Does strict typing improve performance or is this just preference?

#6

Just preference types have no effects on code after it’s run

#7

Would you mind sending a screenshot of where exactly this warning is? (Also showing details etc the warning message)

It seems as if Declarations always needs a boolean value.
This might be an issue, if this is a Fusion feature, you should create an issue about it / comment on the PR on making Fusion strictly typed on GitHub.

This isnt the real fusion, just a copy i put the code at the start of the post, and declarations shouldn’t need a bool value, but the linter thinks the tables should be the same type which is what im trying to fix/silence
