## **What is ES2022?**

For those who don’t know, ES2022 OR EcmaScript 2022 is standard for scripting developed with the cooperation of **Netscape and Microsoft** and mainly derived from Netscape's JavaScript, the widely-used scripting language that is used in Web pages to affect how they look or behave for the user.

\
It’s abbreviated to ES1, ES2, ES3, ES5, and ES6. Since 2016 new versions are named by year (ECMAScript 2016 / 2017 / 2018).

```javascript
const fruits = ['apple','banana','mango','custard'];
```

\
Now, let say we want to access the last element of `fruits` array, but what if you don't know length of array.

\
How will you do that? \n 

Well, there are different approaches to achieve this:

\

1. **__Using length property of array:__**

   \

```javascript
let lastElement = fruits[fruits.length - 1]; console.log(lastElement );
```


---

\

2. **Using the slice() method:**

   \

```javascript
let lastElement = fruits.slice(-1);console.log(lastElement );
```


---


3. **Using the pop() method:**

   \

```javascript
let lastElement = fruits.pop();console.log(lastElement);
```


---

But if you look into this method, this method’s main objective is not to output the last element of the array but we are **manipulating** it in such a way that it gives the last element of an array. Also, sometimes, they are performance issues. __[see here](https://flexiple.com/get-last-array-element-javascript/)__


---

So, ECMA2022 brings a new method for us i.e., at(index).

 \n With at(index), you can get the element at the provided`index`. \n See example below \n 

```javascript

 console.log(fruits.at(1));  // apple
 console.log(fruits.at(-1)); // custard
 console.log(fruits.at(2)); // mango
```

Working jsfiddle is __[here](https://jsfiddle.net/imsabir/1dwtv5xq/8/)__ :

\
Interestingly if you do `fruits.at(-0)` it gives you `apple`. 

\
So, merry go round.

Cheers!
