How to change the script correctly?

• 0
  There is a script that alternately changes 2 numbers, I found it, and I have been using it for a long time, but now the task is to change 3 numbers in turn, but I can't modify the script, how to do it correctly?
  & lt; a id = "phone" href = "" & gt; & lt; / a & gt;
  

  document.addEventListener('DOMContentLoaded', function() {
  	var link = document.getElementById('phone');
  	var a = '+38 (095) 123 45 67';
  	 var b = '+38 (098) 123 45 67';
  	link.innerText = b;
  	link.setAttribute('href', 'tel:' + b);
  	setInterval(function() {
  			link.innerText = link.innerText === b ? a : b;
  			link.setAttribute('href', 'tel:' + link.innerText);
  		  }, 2000);
  	});

  You can add as many numbers as you like to numbers, they will spin in a circle.
  
  

  document.addEventListener('DOMContentLoaded', () => {
  
    const link = document.querySelector('#phone');
  
    let activeIndex = 0;
  
    
  
    const numbers = ['+38 (095) 123 45 67', '+38 (098) 123 45 67', '+38 (111) 111 11 11'];
  
    setNumber(numbers[activeIndex]);
  
    
  
    setInterval(() => {
  
      setNumber(numbers[activeIndex]);
  
      activeIndex = (activeIndex + 1) % numbers.length;
  
    }, 2000);
  
    
  
    function setNumber(number) {
  
      link.innerText = number;
  
      link.setAttribute('href', 'tel:' + number);
  
    }
  
    
  
  });

  document.addEventListener('DOMContentLoaded', function() {
  
    let numbers = [
  
      '+38 (095) 123 45 67',
  
      '+38 (096) 123 45 67',
  
      '+38 (097) 123 45 67',
  
      '+38 (098) 123 45 67',
  
      '+38 (099) 123 45 67',
  
    ];
  
    
  
    function getNumber(numbers){
  
      numbers.push(numbers.shift());
  
      
  
      return numbers[0];
  
    }
  
    
  
    function setNumber(number){
  
      let link = document.getElementById('phone');
  
      link.innerText = number;
  
      link.setAttribute('href', 'tel:' + number);
  
    }
  
    
  
    function update(){
  
      setNumber(getNumber(numbers));
  
    }
  
    
  
    update();
  
    
  
    setInterval(update, 2000);
  
  });
