Progress bar not working with javascript and bootstrap

I am learning bootstrap 4 and I saw progress bar.So, i though to make it more iteractive using javascript. But,my progress bar is not working.I want to move the progress bar upto 100%,like we see normal progress bar moving from 0% to 100%. I tried :

 var count=0;
    var x=document.querySelector('.progress-bar');
     
    window.onload=callMe();
    ;
    function callMe(){
        x.style.width=null;
         setInterval(function(){
              increaseBar();  
        },1000); 
    }


    function increaseBar(){
        count=count+10;
        console.log(count);
        console.dir(x);
       
       x.style.width=count;
      
        x.innerHTML=count;
    }

<div class="container">
  <h2>Progress Bar With Label</h2>
  <div class="progress">
    <div class="progress-bar" style="width:0%">0%</div>
  </div>
</div>

</body>
<script>
   
</script>
</html>

i see that x.style.width=count; is not working and i also tried using x.setAttribute("style,"width"),but it also didnot worked.

You should use percentage for with and clear interwal when reach 100 as percentage

var count=0;var myVar;
    var x=document.querySelector('.progress-bar');         
    window.onload=callMe();
    ;
    function callMe(){
        x.style.width=null;
         myVar=setInterval(function(){
              increaseBar();  
        },1000); 
    }
    function increaseBar(){
       if(count==100){clearInterval(myVar);return}
        count=count+10;         
       x.style.width=count+"%";          
        x.innerHTML=count+"%";
    }
