Sorting An Array Inside An Array Of Objects

Question

Hello I have an array of this form which I am displaying on my meteor template.

var data = [{text_name:'My life', 
score: [{name : 'james',score: 10}, 
        {name : 'john',score : 40},  
        {name : 'Abu',score : 80}]},
        {text_name:'The game real', 
score: [{name : 'penny',score: 30} 
        {name : 'john',score : 20} , 
        {name : 'Abu',score : 30}] }]

I want to sort the score key which is an array of objects in descending order. Using the example data in the text_name:'My life' I want Abu scores to display first because he scored highest.

I have tried sorting by using the code found on this link Sorting an array of JavaScript objects.

That's not valid JavaScript. Please fix so we know what you mean (is it `score:[...`?) Also, if you have tried, post what went wrong. *Also*, why is this tagged [tag:meteor]? — Amadan, May 10 '16 at 01:18
That's not valid JavaScript. A comma is missing after the first `score: 30}`. — Pang, May 10 '16 at 03:11

If I understand correctly, what you're trying to do is have each list sorted within itself.

So here's what you'd need to do:

// iterate over data
for (var i = 0; i < data.length; i++) {
  var item = data[i];
  // sort the item's score
  item.score.sort(function(a, b) {
    return b.score - a.score;
  });
}

Try using the sort method:

Also note, that as the comments have mentioned that is not valid JS, I added the correct format in the example posted above.

Working example

var d = data.map(function(d) {
  return d.score.sort(function(a, b) {
    return a.score + b.score;
  });
});
