Here's how I solved mine with additional scenarios.

Here's how I did it on this exercise. I had gone to a different approach from Dave.

Scope:

  • non-case sensitive search
  • returns nearest point of search (e.g. searches for Ezekiel instead of Ezekiel Dela Peña will return object with name property Ezekiel Dela Peña) [my code has a downside though]
  • returns a student not found.
function print(message) {
  return document.getElementById("output").innerHTML = message;
}

var html = "";
var search = prompt("Enter student name [e.g: Ezekiel] : ").toLowerCase();


var students = [
  {
    name : "Ezekiel Dela Peña",
    track : "Android Development",
    achievements : 23,
    points : 4294
  },
  {
    name : "Mary Madaloiuse",
    track : "Web Design",
    achievements : 27,
    points : 5523
  },
  {
    name : "Fhrey Aston",
    track : "IOS Development",
    achievements : 13,
    points : 1032
  },
  {
    name : "Jarren Quatz",
    track : "Game Development",
    achievements : 60,
    points : 10563
  },
  {
    name : "Aishan Adolfo",
    track : "Front End Development",
    achievements : 3,
    points : 120
  },
];


for(var i = 0; i < students.length; i++) {
  // if student["name"] contains search value. Prints it's info. 
  // else continue searching
  if(students[i].name.toLowerCase().indexOf(search) != -1) {
    for(var key in students[i]) { 
      if(key == "name") {
        html += "<h3><strong>" + key + " : " + students[i][key] + "</strong></h3><br>";
      } 
      else {
        html += "<h3>" + key + " : " + students[i][key] + "</h3>";
      }

      if(key == "points") {
        html += "<br>";
      }
    }
    break;
  } 
  else if(i+1 >= students.length) {
    html += "<h2>Student " + search + " was not found in our end.</h2>";
  }
}

print(html);

Maybe you could use a for loop and the push method to store all student name in an array: const names = []; for(let i = 0; i < students.length; i+=1){ names.push(student[i].name); } After you can do something like: if(names.indexOf(search) != -1){ //and after you may use a for in loop to prints all the properties of the student object } Put best answer if that respond to your question!
