A performance comparison picture between 1.0.0 and 1.1.0:
Also I added a new creator store link to make getting the module easier, make sure to check it out!
Updated the documentation with some new features and fixes, and updated the main post with a comparision.
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class
local Car = class "Car" {
Public = {
Brand = "Lamborghini",
},
Private = {
License_Plate = "XXXX"
},
changeLicensePlate = function(self, plate:string)
self.License_Plate = plate
return self
end,
}
local newCar = Car.new()
newCar:changeLicensePlatw(“YYYY”)
can i do it like this?
Oh no, that would give an invalid access specifier error. Members must always be placed inside access specifiers. Try putting the function inside an access specifier, for example, Public like below:
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class
local Car = class "Car" {
Public = {
Brand = "Lamborghini",
changeLicensePlate = function(self, plate: string) -- We put this function inside the Public Access Specifier, so it can be accessible from everywhere.
self.License_Plate = plate
end,
},
Private = {
License_Plate = "XXXX"
},
}
local newCar = Car.new()
newCar:changeLicensePlate("YYYY")
Check out the documentation for more information access specifiers! You should read the entire thing through, it would be very useful.
object’s Private and Protected access specifiers.final and abstract functions to now accept multiple classes with a new syntax.Util.inClassScope function now accepts a new optional defaultLevel value that determines the default call stack level the function will start doing the checks on.A performance comparison picture between 1.1.0 and 1.2.0:

Make sure to get the latest version to get the most amount of performance, and fixes!
I have put a tool into the .new() function and constructor function, its says This class has no member named “Tool”.
Can you send the script here so I can take a look?
Forgot to include, I’ve updated the API Reference a little bit to show the properties in a better style.
This is the script:
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectionService = game:GetService("CollectionService")
local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class
local toolClass = class "Tool" {
constructor = function(self, tool)
if tool and tool:IsA("Tool") then
self.Tool = tool
self.Configuration = require(self.Tool.Config)
self.Tool.Equipped:Connect(function()
self.equipped = true
end)
self.Tool.Unequipped:Connect(function()
self.equipped = false
end)
end
end,
Public = {
equipped = false,
Tool = nil,
Configuration = {},
}
}
CollectionService:GetInstanceAddedSignal("Tool"):Connect(function(tool)
if tool:IsA("Tool") then
local newTool = toolClass.new(tool)
end
end)
This is the Error : {Class++}: This class has no member named "Tool".
I see what you mean now, this is a common mistake that people encounter when creating classes using my module.
This is mostly related on how dictionaries work in Luau, when you set a key to nil, you’re actually removing that key from the table. In this case, the key Tool is being set to nil in the Public access specifier, and since you’re setting the key Tool to nil, Lua automatically removes it from the table, which in the final classData, the Tool member does not exist.
To solve this issue, instead of setting it to nil, you can set it to false.
Here’s your updated code:
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectionService = game:GetService("CollectionService")
local ClassPP = require(ReplicatedStorage["Class++"])
local class = ClassPP.class
local toolClass = class "Tool" {
constructor = function(self, tool)
if tool and tool:IsA("Tool") then
self.Tool = tool
self.Configuration = require(tool.Config)
self.Tool.Equipped:Connect(function()
self.equipped = true
end)
self.Tool.Unequipped:Connect(function()
self.equipped = false
end)
end
end,
Public = {
equipped = false,
Tool = false,
Configuration = {},
}
}
Oh man i didnt know this about dictionaries, thank you. 
local class, final = ClassPP.class, ClassPP.final
local Test = class "Test" {
Public = {
test = final(function(self, ...)
print(self, ...)
end),
}
}
A performance comparison picture between 1.3.1 and 1.4.0:
Class++ is finally complete and out of beta! I can’t really think of adding any new features, so this is going to be the last version for now.
Until I get a new idea or find an efficient method to implement certain ideas that I currently have, the only updates there will ever be are performance updates and bug fixes. (And maybe some internal changes)
Thanks for using my module!
final keyword now works as it was in 1.3.1)If you have any new feature ideas, or found bugs, please don’t hesitate to create a feature request or a bug form though!
Updated the documentation page to give a better explanation on the Type API!
class type.(@arbitiu turns out it was possible lol.)
unluckiest timing 
, having released this barely a week ago
Well it’s still in beta, so I think I have plenty of time to fix things up, but I didn’t know it would be this broken
