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?

You could use Array#slice with negative value for the last items.

array.slice(-5).forEach()
