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 can use if inside forEach – Naveed Aheer Commented May 2, 2017 at 11:49
• Use for loop starting at the end and counting down (i--) with correct condition – Esko Commented May 2, 2017 at 11:49

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

array.slice(-5).forEach()
