## Overview
The **`set.size` property** in JavaScript returns the number of elements in the stack. In other words, this property is used to get the current size of the set. 

The following illustration shows the visual representation of the `set.size` property:

---
 In JavaScript, a **`set`** is a particular instance of a list in which all inputs are unique.

---

> **Note**: If there are duplicates, then the set will only keep the first instance. For example:
`{'Tom','Alsvin','Eddie','Tom'}` will result in `{'Tom','Alsvin','Eddie'}`.

#   
## Syntax

```javascript
set_name.size
// where the set_name is the name of the set.
```
## Parameter

This property does not require a parameter.

## Return value
The `set.size` property returns the number of elements in the set. 

## Code
The code below shows how to use the `set.size` property in JavaScript:

const set_1 = new Set(["Tom","Alsvin", "Eddie"]); 
//set containing value
console.log("The size of set_1: ",set_1.size);

//empty set
const set_2 = new Set(); 
console.log("The size of set_2: ",set_2.size);



## Explanation
-  **Line 1**: We create a set with three values `{'Tom','Alsvin','Eddie'}` and name it `set_1`.

- **Line 3**: We check the size of `set_1`, which contains elements, using `set_1.size`. 

- **Line 6**: We create an empty set i.e. `set_2`. 

- **Line 7**: We check the size of `set_2`, which is empty, using `set_2.size`.
