How the get the last element in an array items using JavaScript

Question

I have a list of array items like this:

const items = [
  { a: 1 },
  { b: 2 },
  { c: 3 },
]

How can I return / log the last element: { c: 3 }

Here's what I've tried so far:

let newarray = items.map((item) => {
    console.log(item);
})

console.log(newarray);

Answer 1

Update 2021+

You can use the Array.at() method, which was moved to Stage 4 in Aug, 2021.

['a','b','c'].at(-1) // 'c'

This is often referred to as relative indexing which...

takes an integer value and returns the item at that index, allowing for positive and negative integers. Negative integers count back from the last item in the array.

Answer 2

just log the length minus 1, nothing to do with es6:

console.log(items[items.length - 1])
