Quick Tip: How to get the first and last element in an Array using JavaScript

You can use the find() and findLast() methods in JavaScript to get the first and last element in an array.

Here's an example.

<script>
  const arr = [6, 18, 21, 81, 13];
  
  document.write('the first value is ' + arr.find(item => item));       // Output 6.	
  document.write('the last value is ' + arr.findLast(item => item));	// Output 13.
</script>

Try it

You can also add some conditions like, get the first and last values (or elements) that is greater than 5.

<script>
  const arr = [3, 7, 51, 3, 17, 6];
  
  document.write('the first value is ' + arr.find(item => item > 5));	    // Output 7.
  document.write('the last value is ' + arr.findLast(item => item > 5));    // Output 6.
</script>
