Modifying text dynamically in AngularJS by cycling through an array of strings

Question

Modifying text dynamically in AngularJS by cycling through an array of strings

Is it possible to create a text carousel in my angular controller without using an infinite loop?

For example:

 //html 
 <span> {{ notes }}</span>

 //angular controller

   var i = 0;
   var array = ["A", "B", "C", "D", "E"];

   while (true) {
       $scope.notes = array[i];
       i = i + 1;
       if (i = array.length - 1) {
           i = 0;
       }
   }

I want to have a vertical text carousel with fade animations using CSS classes. Are there alternative methods to achieve this result?

It appears that you are in need of the $interval service.

let count = 0;
let elements = ['Apple', 'Banana', 'Cherry', 'Date', 'Elderberry'];

$interval(function () {
  $scope.result = elements[count++ % elements.length];
}, 1000);

Instead of using an infinite loop, I recommend utilizing setInterval and incorporating % to properly wrap your index

let index = 0;
const letters = ["A", "B", "C", "D", "E"];

function rotateLetters() {
  let idx = ++index % letters.length;
  $scope.notes = letters[idx];
}

setInterval(rotateLetters, delayTime);
