Found some errors in this practice session

I'm not sure what the best way for me to share feedback about errors in the course material is. If this isn't the place, please let me know.

While loops practice errors:

  1. doWhileLoops.js says while instead of do while throughout the instructions

  2. The Treehouse solution to the whileLoops practice starting on line 81 of that file is flawed. The instructions require that the loop print the number 8 if it is randomly generated, even if it is generated the first in the sequence. By setting i randomly before the loop, you run the risk that i will equal 8 before we enter the loop and in that case, the loop will not run and 8 will not print. Alternative solution:

// between 0 and 9. Stop building the string when the number 8 comes up.
// Be sure that 8 does print as the last character. The resulting string 
// will be a random length.
print('5th Loop:');
text = '';
i = 0;

function randomNum() {
  return Math.floor(Math.random() * 10);

// Write 5th loop here:

while(i !== 8) {
  i = randomNum();
  text += i + ' ';

print(text); // Should print something like `4 7 2 9 8 `, or `9 0 8 ` or `8 `.
