lua - 零检查，最好的方法？

Question

刚学lua，看到这两种检查nil的方法

local stats = game.ServerStorage.PlayerMoney:FindFirstChild(player.Name)

if (stats ~= nil) then 
    -- do stuff
end

if (stats) then 
    -- do stuff
end

if 语句是否等价？如果是这样，包含额外的“~= nil”部分有什么好处吗？

Answer 1

语句“~= nil”在 stats = false 时也有效。

您可以阅读 docs :

The condition expression of a control structure can return any value. Both false and nil are considered false. All values different from nil and false are considered true (in particular, the number 0 and the empty string are also true).
