How to Access the Last Element of an Array in JavaScript ?
In JavaScript, you can access the last element of an array using the array’s length property. Here are a couple of ways to do it:
Table of Content
- Using Array Length
- Using the pop Method
- Using array slice method
Using Array Length
Use the length property to get the last element by subtracting 1 from the array’s length.
Example: Below is an example.
let myArray = [1, 2, 3, 4, 5];
let lastElement = myArray[myArray.length - 1];
console.log(lastElement); // Outputs 5
Output
5
Using the pop Method
The pop method removes the last element from an array and returns that element. If you just want to access the last element without removing it, you can use this method in combination with a temporary variable.
Example: Below is an example.
let myArray = [1, 2, 3, 4, 5];
let lastElement = myArray.pop();
console.log(lastElement); // Outputs 5
console.log(myArray); // Outputs [1, 2, 3, 4]
Output
5 [ 1, 2, 3, 4 ]
Using array slice method
In this approach we use array slice method. Here we pass a negative index to slice, like -1, it starts the extraction from the end of the array and we access last element from 0’th index.
Syntax:
lastelement= array.slice(-1)[0]
Example: In this example the slice method to access the last element of the array. The slice(-1) returns an array containing the last element, and [0] accesses that element.
let array = [1, 2, 3, 4, 5, 6];
let lastElement = array.slice(-1)[0];
console.log(lastElement);
Output
6
