Front End Web Development Techdegree Student 21,661 PointsJesus Mendoza But, how can i while i am in for loop?

var students = ['Sascha', 'Lynn', 'Jennifer', 'Paul'];
for (var i = 0; i < 3; i++) {
console.log(students[i]);
}
Note that instead using
i < students.lenght
on the foor loop I used
i < 3

23,288 PointsYea Melissa you're and Chris are right! It seems that I did not understand the question.

var listOfItems = ['Item 1', 'Item 2', 'Item 3', 'Item 4'];
for (var i = 0; i < listOfItems.length; i++) {
if ( i === 2 ) {
console.log(students[i]);
}
}
This will print to the console the third item in the list

for (var i = 0; i < students.length; i++){ if (i === 2){ // The third item is index # 2 console.log(students[i]); // This will send the 3rd Student in the array to the console. } }
