My code took too long to run (??)

Is this because my code is wrong or because my internet speed is horrendous?

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

You forgot to update count in the while loop, so count < 26 will always evaluate to true, locking the program in an infinite loop.

ah very good! I couldn't for the life of me work out if there was something missing or not. Code blind!

Thanks

Yup, the loop needs a way to break out. You need a way of changing the value in the code so that eventually the while condition will be false ensuring the loop will end!. :-)
