Hi, on line 20 i used for ( let i = 0; i <= 3; i++ ) {
i didnt use questions.length as quil did my code ran correctly.

I feel that although my code is good maybe if i wanted to ask more questions (say 3 more) i'd have to update my <= 3; to <= 6. Is that why guil uses questions.length as it automatically updates depending if there are more or less questions?

You are absolutely right. The length property is always going to return a total number of elements in an array. This way you don't have to hard code the length.
