hey. thanks for your answer. i understand the idea, but i dont get the 3rd line "get a random number% size". im , begginer in javascript, coule you help/show me this function please?

Answer 3

create a random number.
there aren't many ways to do this. when you do
rn % size. it forces that number to be [0, size-1] which are the indexes of your array.a pure ransom function will return a large number.
dont know php well enough to tell u what the generator syntax is. ull have to look it up :/
