JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge

Students list challenge. Not sure how to go further

Hello folks!

I am stuck (as always). I was excited I powered through the first steps, just to hit a wall. I'd like to have some help if possible, a feedback, but not a solution.

Could you please provide a little push, so that I can move in the right direction?

That's what I've built so far. I am not sure if all of this is necessary. However, I am able to log all the names in a new Array. What I want to do is to print the name that the user writes in the prompt dialog.

var userType = "";
var studentsList = ["jack", "alex",  "robert", "jill" , "angus"];
var quit = "quit";
var newStudentsList = [];

var students = [

  {name: "jack", track: "iOS", achievement: 5},
  {name: "alex", track: "Javascript", achievement: 7},
  {name: "robert", track: "Python", achievement: 0},
  {name: "jill", track: "Ruby", achievement: 15},
 {name: "angus", track: "C++", achievement: 3}
];


while (true) {

        var input = prompt("student name please"); 
        if ( input === "quit") {
  break;


        } if (studentsList.indexOf(input) > -1) { 
for (var i = 0; i < students.length; i++) {

  newStudentsList.push(students[i]);
}
  console.log(newStudentsList);

} 
}

The program asks questions in a loop. If the user writes a name that is in the system, then there's a match and all the students get logged in the console. Somehow I have to tell the system : write the information about the student you typed in.

In which direction should I move?

As always, I do appreciate your time!

Thanks, A.

Here's a few hints (no code):

The prompt should be done before the search loop. This allows the program to check each name for a match without asking for more input. If you want to be able to do more than one search, you'll need another loop around everything.

You'll also need a process to convert the contents of a student object into a string to make it visible on the page. In the next video this is done in a function.

Hello Steven,

I was wondering where you've been! I always see you around, and I was just reading about some answers you left to other students.

I am sometimes surprised on how simple is the solution. I find myself thinking about crazy calculations when it could be done in two lines of code.

Thanks for your answer, I appreciate your support!

I am posting here my solution for anyone interested in knowing more about the challenge. This is not as dry as some responses here, because I am asking the system to store the answer to a new Array, which is not needed. I am also not using a nice styled message at the bottom, or .toLowerCase() as an option, however the core of the program is there

var userType = "";
var quit = "quit";
var message = '';
var students = [

  {name: "jack", track: "iOS", achievement: 5},
  {name: "alex", track: "Javascript", achievement: 7},
  {name: "robert", track: "Python", achievement: 0},
  {name: "jill", track: "Ruby", achievement: 15},
 {name: "angus", track: "C++", achievement: 3}
];


while (true) {

        var input = prompt("student name please"); 
        if ( input === "quit") {
  break;

      } for (var i = 0; i < students.length; i++) { 

 if ( input === students[i].name) { 

   var newArray = [];
   newArray.push(students[i].name + " " + students[i].track + " "+  students[i].achievement)
  alert(newArray);
}
}
}
