Question

Consider a JavaScript object with keys first, last, and score, representing a student. The values of first and last are both strings (for first and last name respectively), while the value of score is an integer.

For example: {first: "John", last: "Smitt", score: 20}

Write a JavaScript function named maxName that, given an array of such objects, returns a string consisting of the full name (first and last) of the student with the largest score.

For example:

a = [
{first: "John", last: "Smith", score: 20},
{first: "Liza", last: "Hernandez", score: 50},
{first: "Mary", last: "Jones", score: 10}];
maxName(a) //=> "Liza Hernandez"

function maxName(obj){
  // assume largest to be the first score
  var largest_score_pos = 0;

  // compare this to all other scores
  for(var i=1;i<obj.length;i++){
    if(obj[largest_score_pos].score<obj[i].score){
      largest_score_pos=i;
    }
  }

  //largest_score_pos now contains the position of the person with largest score
  return obj[largest_score_pos].first+" "+obj[largest_score_pos].last;
}
a = [
{first: "John", last: "Smith", score: 20},
{first: "Liza", last: "Hernandez", score: 50},
{first: "Mary", last: "Jones", score: 10}];
console.log(maxName(a))
