But not anymore!!
Today’s Geeks! I am here with the best solution for this.
And I personally believe that asking the question or finding the answer to your question is the best way to learn. So, I congratulate you that you are on the right track in your learning journey. So now, I will definitely be going to help you in the best way.
So, let’s start with the new concept!
- First, it is possible that an array may hold values of distinct types. It means you can have an array that stores the string and number, and also the boolean values.
- Second, the array’s length is auto-growing and dynamically sized. Or we can say that you don’t require defining the array size upfront.
Now, check what I will answer you today!
Top 3 methods for JS get last element of array
array length property
Let’s take an example of it:
The at() method is useful for taking an integer value and it will return the value at that particular index. Here users can define positive or negative integer values. But you have to keep in mind that the negative integer will count back from the last array element.
Let’s understand it with an example:
Another easy and simple method to get JS last element of array is:
Let’s take an example of it for a better understanding.
Note: It will not include the element of the ending element’s index.
In the below example, I will find the third last element of the array.
Here, I have tested them and shown you the result. This will help you to know how these methods work.
Note: I have used the console.time and console.timeEnd method to test the time taken by the individual function.
array length property: 0.15380859375 ms
array at property: 0.197998046875 ms
array slice method: 0.442138671875 ms
array pop method: 0.255126953125 ms
As you can see the length() method is quite faster as compared to other methods. Therefore, you can use it to get faster results.
I have also mentioned the test results of each method that help you know which method is faster. Now, you can use any of them from these methods at your convenience.
