JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops Create a while Loop

JavaScript Loops, Arrays and objects challenge task 1

so the task is as follows: "In this challenge, you will create a while loop that prints to the document 26 times. We've added a variable named count, use it to track the number of times the loop runs. Don't forget to use the document.write() method inside the loop."

My question is what are we expecting to write to the document here? The question is very ambiguous in that sense.

When I try to submit my code it tells me that there is a syntax parse error, however when I run my code through the browser it works fine.

let count = 0;
while ( count < 26 ) {
  document.write(  );

While it is better to use let instead of var the challenges sometimes don’t like it when you change their code. Just change it back to var count = 0; and it will pass.

Yes that worked, thank you. I guess I'm that used to just using let and const now that I change them without thinking

Yeah it seems best not to change their code unless it specifically says too. It just confuses their logic.
