JavaScript - 是否可以限制forEach循环给出的结果？

Question

I have a very long JSON array that I fetch using a forEach loop where I need to display only the last 5 elements.

  array.forEach(showOnlyFiveElements => {
   //only 5 elements should be show here
  });

Can't it be done using a forEach ? Or I should go for something different?

您可以使用带有负值的Array#slice作为最后一项。

array.slice(-5).forEach()
