For loop only returns last number

June 23, 2022

I have made a for loop in order to console log multiple entries in an array. The for loop, however, only returns the last entry in the array, instead of everything from 0 to end of array.

for (var i = 0; i < roa.length; i++) {questionContentRoa = roa[i].questionContent, correctAnswerRoa = roa[i].correctAnswer }
                console.log(questionContentRoa, correctAnswerRoa);

>Solution :

It will be clearer to you if you ident the code a little bit.

The console.log is outside of the scope, hence, it’s only logging the last assignment before the loop ends.

for (var i = 0; i < roa.length; i++) {
    questionContentRoa = roa[i].questionContent;
    correctAnswerRoa = roa[i].correctAnswer;
}
console.log(questionContentRoa, correctAnswerRoa);
