function randomNumb() { return Math.floor(Math.random() * 10) + 1; }
var guess; var random = randomNumb(); var count = 0;
do { guess = prompt("Number from 1 - 10"); count += 1; } while (parseInt(guess) !== random)

You'll find that most programs can be condensed and optimized. The examples in the courses have a primary objective of conveying concepts clearly, so they will often use a few extra steps and variables to make sure what is happening is easily understood.
In real world programming, optimization will often be more important; but caution should be exercised to avoid creating code that obscures its functionality. This can make future maintenance difficult, particularly if it will be performed by other parties.
