Remove object based on a key from array of objects

Question

Below is the json :

var data= {
    'A' : {
        'Total' : 123,
        'Cricket' : 76,
        'Football' : 12,
        'Hockey' : 1,
        'None' : 10
    },
    'B' : {
        'Total': 123,
        'Cricket': 76,
        'Football': 12,
        'Hockey': 1,
        'None': 10
    },
    'C' : {
        'Total': 0,
        'Cricket': 76,
        'Football': 12,
        'Hockey': 1,
        'None': 10
    }   
}

I want to remove C in which value of total is zero,,

$.each(json, function (key, value) {
    if (value.Total === 0) {
        //delete
    }
});

I have tried various ways but didnt work

by the way, that's not JSON, that's just a javascript object, if it were JSON, you'd have to JSON.parse it before doing anything more — Jaromanda X

Use delete keyword to delete a property in an object.

var json = {
  'A': {
    'Total': 123,
    'Cricket': 76,
    'Football': 12,
    'Hockey': 1,
    'None': 10

  },
  'B': {
    'Total': 123,
    'Cricket': 76,
    'Football': 12,
    'Hockey': 1,
    'None': 10
  },
  'C': {
    'Total': 0,
    'Cricket': 76,
    'Football': 12,
    'Hockey': 1,
    'None': 10
  }
}

$.each(json, function(key, value) {
  if (value.Total === 0) {
    delete json[key];
  }
});

console.log(json);
