How to make multiple classes in a list to do a function?

I do not know how to do this. I know how to set it up It's something like

init = function()
    bananas = []
end

update = function()
    if keyboard.press.SPACE then
        bananas.push( new banana(tree_x, tree_y))
    end
end

Are you trying to have all the classes in a list execute a function? If so, you can do it like this: for x in bananas x.grow() end

you have to use this code structure

   for obj in list 
      obj.method()
   end

or

   list.forEach( function( obj ) obj.method() end )

The condition for success of this code is that all objects in the list have the method you want to call. It is best if the list includes objects that are created from one class.

Thanks, I got stuck because it kept saying that "grow" was not a function, I was confused so I checked the function and it said

groww = function()
   //code
end

Also @apinguen, you can use 3 backticks to represent code, ( what's a backtick, this " ` ")

its like

backtick backtick backtick

code

backtick backtick backtick
