Why don't you try to use Console on your browser? The code in your task doing this way:

var x = 0; do { console.log('I love JavaScript'); x += 1; } while ( x <= ... )

  1. x before loop equal 0
  2. do "console.log(text); x = x+1;" 3 while ~ if( expression === true ). In "do ... while ..." case we get 1 string even if expression is false.

That's why while( expression ) more preferable and you should understand the difference between. do {} while () - do first then check if true vs. while () {} - check first then do if true

Hope it was helpful.
