It's easy to forget to initialize a local variable and then proceed to use it regardless. This can happen due to a typo, or sometimes it can happen because the original variable definition is shadowed. When a local variable doesn't have an initial value and is used without ever being assigned to, this warning is emitted:
```
```lua
local foo
if foo then -- Variable 'foo' defined at line 1 is never initialized or assigned; initialize with 'nil' to silence
print(foo)
end
```
## DuplicateFunction (21)
This warning is emitted when a script defines two functions with the same name in the same scope.
The warning is not produced when the functions are defined in different scopes because this is much more likely to be intentional.
```lua
function foo() end
function foo() end -- Duplicate function definition: 'foo' also defined on line 1
-- OK: the functions are not defined in the same scope.
if x then
function bar() end
else
function bar() end
end
```
