My answer with console.log without functions and pretty simple. maybe I should use a function but here's my solution.

Question

// Loop prompt
    while (true){
        var answer = prompt('insert the student');
            if (answer == 'quit'){
                break;
            }
        //looping the array of object
        for (var i=0; i < students.length; i++){

            if(students[i].name == answer){
                //console the students if match
                for (prop in students[i]){
                    console.log(prop +": "+ students[i][prop]); 
                }
                var checkNo = ''; //to check if doesn't exist and avoid repetition if one student is not in the array
            }
        }
        //if is no blank there is not student. kind of return true when finish.
        if (checkNo != ''){
            console.log('No students with this name!');
        }
    }

Hey James,

When you're programming, try to think about what the user is going to see with your program. If someone didn't know JavaScript and ran your program as is, they would have no idea how to quit the program. I'm sure they would eventually type in quit to the box, but you need more information if you're just going to use "quit" as the breaking point of the student search.

Personally, I would use the natural cancel button that is on the prompt to exit out of the loop. All you have to do is check for any falsey value because when you click cancel on a prompt it will return a falsey value such as null or "":

//if answer is any falsey value
if (!answer) {
//break out of the loop
break;
}

I also noticed that checkNo isn't actually used. Your if statement will never execute because checkNo will always be an empty string with your current code. The easiest way to use checkNo would be set to as a boolean instead of an empty string and set your variables at the beginning. Set it to true/false depending on how you wanted to do it. I would set checkNo to be false at first and only true if a student isn't found.
