Javascript program flow in a loop and how to "reset" a variable?

while (true) {
  search = prompt('Search student records:');
  if (search === null || search.toLowerCase() === 'quit') {
    break;
  } 
  // for loop to cycle through the students array to match with the users search
  for (var i = 0; i < students.length; i++) {
    student = students[i];
    results.pop(students);
    if (student.name.toLowerCase() === search.toLowerCase() ) {
      results.push(student[i]);
      message = getStudentReport(student);
      print(message);
    }
    if (results.length < 1) {
    message = "<h2> Sorry, that person does not exist in our records. </h2>";
    print(message);
    }
  }
}
