Get the first and last item in an array using JavaScript
In this article, we will learn to get the first & last element in an array in Javascript, along with understanding their implementation through the examples.
Javascript array is a variable that holds multiple values at a time. The first and last elements are accessed using an index and the first value is accessed using index 0 and the last element can be accessed through length property which has one more value than the highest array index. The array length property in JavaScript is used to set or return the number of elements in an array.
Example 1: This example illustrates to access the first and last number in the array.
Javascript
<script> // Array let s=[3, 2, 3, 4, 5]; function Gfg() { // Storing the first item in a variable let f=s[0]; // Storing the last item let l=s[s.length-1]; // Printing output to screen document.write( "First element is " + f); document.write( "<br> Last element is " + l); } Gfg(); // Calling the function </script> |
Output:
First element is 3 Last element is 5
Example 2: This example illustrates to access the first and last word in the array.
Javascript
<script> // Simple array let s= [ "Geeks" , "for" , "geeks" , "computer" , "science" ]; function Gfg() { // First item of the array let f=s[0]; // Last item of the array let l=s[s.length-1]; // Printing the output to screen document.write( "First element is " + f); document.write( "<br> Last element is " + l); } Gfg(); // Calling the function </script> |
Output:
First element is Geeks Last element is science
