Hei Abdullahi,

You will have to increment the counter variable at the end of the while loop like this:

count+=1 or count ++

Hi Abdullahi! Your code takes too long to run because you have created an infinite loop. "count" always is going to be less than 26 because nothing changes inside the loop. You need to add count +=1; or count++ (which is the same). So after first run var count = 1, after second run var count =2 and so on. Until it reaches 26. Hope this helps.

var count = 0;
while (count < 26) {
   document.write(count); 
   count+=1;
}
