To be fair Lua also made some bad decisions, though maybe not as bad as javascript:

- tables being used for both objects and arrays can create a lot of confusion, especially when you have some integer keys, but not all, and especially when they are not consecutive or one of them is 0 - indexes start at 1 - assigning nil deinitializes variables/entries instead of assigning the value `nil` (this becomes especially bad if you mistakingly try to use nil as a value in an array/table) - nil and false are falsy, but not 0, which instead is truthy
