## Overview

The **`plusElement()` method** creates a new `List` by combining the current `MutableList` and the passed element.

## Syntax

```kotlin
fun <T> Iterable<T>.plusElement(element: T): List<T>
```
## Parameter

This method takes the element to be added as an argument.

## Return value

This method returns a new `MutableList` created by combining the invoking `MutableList` and the passed element.

## Code 

The code below demonstrates how to use the `plusElement()` method in Kotlin:

fun main() {

  val list: List<Int> = mutableListOf(1, 2, 3, 4)
  println("The list is : $list")
  
  val newList = list.plusElement(5);// [list elements + 5]
  println("list.plusElement(5) : $newList")

}

## Explanation 

In the above code:

- **Line 3**: We create a new `MutableList` object with name `list` using the `mutableListOf()` method. For the `mutableListOf()` method, we provide `1,2,3,4` as an argument. All the provided arguments are present in the returned `list`. The list is `[1,2,3,4]`.
- **Line 6**: We use the `plusElement()` method with `5` as an argument. This creates and returns a new `List` by combining the elements of the `list` variable and `5`. The returned list is `[1,2,3,4,5]`.

How to use the plusElement() method of MutableList in Kotlin

Combines a MutableList with a new element to create a new List. Example: `[1,2,3,4].plusElement(5)` yields `[1,2,3,4,5]`.
