JavaScript Basic Evaluation

I've been given a couple simple tasks for an evaluation that I'd like to verify.
1) The first is :
Please implement a JavaScript function called “thisisaloop” that initializes a variable called ‘dl’ with a value of ‘0’ and uses a for loop to increment the value of ‘dl’ by 1 on each iteration. Allow the for loop to execute until ‘dl’ possesses a value of ’10’, then have the function return the value of the ‘dl’ variable.

Here is my answer- will this work?
function thisisaloop()
{
var dl=0;
for (var i=0;i<10;i++)
{
dl=dl+1;
}
return dl
}

2) The second is to point out the errors in a JavaScript below. It is meant to run a while loop that adds 1 to the value of the 'dl count' variable upon each iteration, then returns the value of 'dl count' when the value reaches 100.

Line #
01 <script type="text/javascript">
02 var result = dlRules(0);
03
04 function dlRules (dl_count) {
05     var limit = 100;
06     match = 1;
07
08     while (dl_count != limit)
09              dl_count ++ match;
10              if (dl_count == 95) {
11                       dl_count = 10;
12              }
13     }
14 return (dl_count)
15 }
16 </script>
