Javascript on repeat image generator

Question

I want to write an image generator, there are 10 images in total and it will display 5 images randomly each time without repeating, how do I do that???

Answer 1

Make an array of all images and use
Array_name[math.floor(math.random()*array.length)]
Not sure if the formula is correct, but try it

Answer 2

But you can't guarantee math.random() does not generate same numbers, right?😓
