## MisleadingCondition (30)

Luau is very strict about what evaluates to `false`: only `nil` and `false`. Some programmers are not used to this and try to also test numbers, strings, and tables. This warning flags conditions that are likely erroneous:

```luau
--!hidden mode=nocheck
x = 0
-- (num) is always true; did you mean (num ~= 0)?
if x then
end

s = ""
-- (str) is always true; did you mean (str ~= "")?
if s then
end
```
