Guide to substituting the index value with the user's specific choice

Let's simplify this. Suppose I have a list in my ng-repeat 

1. A & index[0]<br>
 2. B & index[1]<br>
 3. C & index[2]<br>
 4. D & index[3]<br><br>

and there is an input field where the user can prioritize the list

For example:

1. B Prior to 1st place... then 

B & index[0]<br>
  A & index[1]<br>
  C & index[2]<br>
  D & index[3]<br>


2. D Prior to 2nd place... then 

A & index[0]<br>
  D & index[1]<br>
  B & index[2]<br>
  C & index[3]<br>

Is there a way to achieve this? Please help. Thank you in advance

An effective way to manage user input is by utilizing an array structure. By storing all options in an array, you can easily adjust the order of elements based on user interactions.

Here is a sample code snippet for implementing this functionality:

var temporaryValue = myArray[currentPosition];
myArray[currentPosition] = myArray[newPosition];
myArray[newPosition] = temporaryValue;
