In this shot, we will learn how to swap variables using destructuring assignment in JavaScript. We will start with a problem statement, followed by an example.




#    
## Problem
Swap the two given variables using the JavaScript destructuring feature.

### Example
Input: `x=5`, `y=10`

Output: `x=10`, `y=5`


#    
## Solution
We will start solving this problem by looking at the destructuring concept.

JavaScript's **destructuring** is used to unpack the values present in arrays or object properties into distinct variables.



//declare and initialize an array
let arr = ["apple","orange"]

//destructing the arrary arr
let [a,b] = arr

//print a and b values
console.log(a,b)

## Explanation
In the above code snippet: 
* Line 2: We declare and initialize an array `arr`.
* Line 5: Using the destructuring assignment, we unpack the values of `arr` and store them in variables `a` and `b`.
* Line 8: We print the values to the console.

//given variables
let x = 5;
let y = 10;

console.log("Before:")
console.log(x,y)

//assign them as array to temp
let temp = [y,x];

//destructure
[x,y] = temp

console.log("After:")
console.log(x,y)



## Explanation
In the above code snippet: 
* Line 2 and 3: We declare and initialize variables `x` and `y`.
* Line 9: We pass `x` and `y` as an array in reverse order and assign it to `temp`.
* Line 12: We destructure the array `temp` and assign it to `x` and `y`.
