I'm unsure of why 10 is the wrong answer if the loop is supposed to run 10 times.

The question reads, "Finish the code in this loop's condition, so that 'I love JavaScript' is printed to the console 10 times". Therefore the answer I submitted was <=10. Why is this incorrect?

var x = 0; do { console.log('I love JavaScript'); x += 1; } while ( x <= 9 )

Here the variable x is initialise with zero. So to run the do block 10 times we have to write 9 in while condition then the condition will be run from 0 to 9. If we write 10 instead of 9 the do block will be run 11 times i.e(0 to 10) in this question.

But if we remove = in while condition like [while ( x < 10 )] then value 10 will be answer.
