如何在 lua 表中调用未命名的 function？ [从桌子外面]

Question

p={update=function(} print("hello") end}

I can call the function within p using p.update() outside the table.

How do I call unnamed functions though? ie

p={function(} print("hello") end}

If I know the index of the function, 1 in this case, can I use that in my function call? like p1? I've tried some variations of this to no success.

Yes. p.update is just syntactic sugar for one-word string keys.

The more general way to index a table is to put the key value in brackets:

p[1]()
