What does it mean to have a variable with no value or equal sign?
Ive seen a lot of variables with no values and looks like this:
local examplevariable local example2variable
And people use these variables as if it did have a value
Also how do people use variables with the value of nil? Is it the same thing?
local examplevariable = nil

It is required in other programming languages to initialize a variable and may cause an error in the compiler. In Lua this is not required. User#5423 17 — 7y

local examplevariable and local examplevariable = nil are essentially the same. The former is what you would call a 'variable declaration' while the latter is both a 'declaration' and 'initialization' of the variable examplevariable to nil. A place you might see this often is with a debounce variable:
local debounce --declaration: at this point it is nil
...
--nil is a 'falsy' value
--line 07 will evaluate to true if debounce is nil
if not debounce then
debounce = true
print("Doing some debounced thing")
wait(1)
debounce = nil
end
