What's he difference between class and THIS?

Alright so here’s what I’m wondering, what’s the difference between class and this:

function classFake()
local Class = {}
return setmetatable(Class, {
__call = function(...)

you can get the class code there https://bitbucket.org/TwoLivesLeft/core/wiki/CodeaClasses

@Jmv38 I understand how to use it, but why does it exist if you can just do the above?

The class is generally easier to use for beginners

@warspyking read the whole link down to the bottom.You’ll see what the class code is. And you’ll see how different it is from your code.
