The Student Record Search Challenge Solution Part2

Initially used the For loop inside the For loop as mentioned in the program below to print all the Property and the Value but I am wondering if that same For loop structure can be used to solve the second part of the challenge?

var students = [
  { Name: 'DJ',
    Track: 'Full Stack JavaScript',
    Achievements: 2,
    Point: 5
  },
  { Name: 'Nick',
    Track: 'HTML',
    Achievements: 2,
    Point: 10
  },

  { Name: 'Pasan',
    Track: 'iOS',
    Achievements: 3,
    Point: 15
  },

  { Name: 'Dave',
    Track: 'JavaScript',
    Achievements: 6,
    Point: 20
  },

  { Name: 'Guil',
    Track: 'CSS Layout',
    Achievements: 4,
    Point: 15
  }
];

for (i=0; i<students.length; i++)/*Loop to access every single element from the array*/{
    document.write('<br>');
  for(var prop in students[i])/*Loop is to access every property from the objects*/{
    document.write(prop, ':', students[i][prop], '<br>')
  }
}

:point_right: A similar loop would naturally be part of the search process.

But there will be additional code involved to test each record for a match with the search conditions and show only the records that match.

The video you created this question from (and is linked to the "watch video" button up top :arrow_upper_right:) shows this process in detail.
