My while loop is not displaying any outputs after making a search from the arrays

I'm able to run it, fill out both Arrays, then input the search criteria but that's it. no results are thrown back.

        var SIZE = 4;
        var actors = new Array(SIZE); //array holding actors
        var roles = new Array(SIZE); //array holding roles
        
        
        for (var i = 0; i < SIZE; i++)  {
        
            actors[i] = prompt ("Please enter your "  + (i + 1) + " favorite Actor");
            roles[i] = prompt ("What role did your " + (i + 1)+ " Actor played?");
        }
                    
        var favorite; // hold search actor name
        var found = false;
        var BR = "<br>";    
        
        favorite = prompt ("Please enter the name of your most favorite actor of all");
        
        while (i < size && !(found))    {
            i++;
        
            if (actors[i] == favorite)  {
                found = true;
                document.write("Your favorite actor " + actors[i] + " played the role of " + roles[i] + BR);
                
        /*for(var i = 0; i < size; i++) {

            if ( favorite == actors[i]) {
                found = true;
                document.write("Your favorite actor " + actors[i] + " played the role of " + roles[i] + BR);
        
            }
        
        }
        */
        if (!found) { //if we find nothing 
            document.write("Sorry, we couldn't find an actor with that name" + BR);
        }

I have tried using for and also while loop but none work, in my head the while loop makes sense. So im not sure whats the issue.

You have to update some parts:

Please use another variable then i in the second loop
Move increase of counter to the end of scope of the second loop
Use SIZE in the second loop, as JS is case-sensitive. Please check the updated example (https://codepen.io/alekskorovin/pen/xxXxYGB):

var SIZE = 4;
var actors = new Array(SIZE); //array holding actors
var roles = new Array(SIZE); //array holding roles

for (var i = 0; i < SIZE; i++) {
  actors[i] = prompt("Please enter your " + (i + 1) + " favorite Actor");
  roles[i] = prompt("What role did your " + (i + 1) + " Actor played?");
}

var favorite; // hold search actor name
var found = false;
var BR = "<br>";

favorite = prompt("Please enter the name of your most favorite actor of all");
let k = 0
while (k < SIZE && !found) {
  if (actors[k] == favorite) {
    found = true;
    console.log(
      "Your favorite actor " +
        actors[k] +
        " played the role of " +
        roles[k] +
        BR
    );

    if (!found) {
      //if we find nothing
      console.log("Sorry, we couldn't find an actor with that name" + BR);
    }
  }
  k++;
}

found the problem thanks to @Teemu, a silly mistake I made

had SIZE declared but later down I was using size.
