合計売上を得る

Question

ブランチのないオブジェクトとブランチあたりの総売上を返す関数を作成しました。

var salesPersons = [ 
     {"name": {"first": "Aleen", "last" :"Atkins"}, "sales" : "$2314", "branch": "Austin, TX"}, 
     {"name": {"first": "Alvaro", "last" :"Angelos"}, "sales" : "$1668", "branch": "New York City, NY"}, 
     {"name": {"first": "Denese", "last" :"Dossett"}, "sales" : "$9248", "branch": "Austin, TX"}, 
     {"name": {"first": "Douglas", "last" :"Denney"}, "sales" : "$5058", "branch": "New York City, NY"}, 
     {"name": {"first": "Earline", "last" :"Erickson"}, "sales" : "$18876", "branch": "New York City, NY"}, 
     {"name": {"first": "Herman", "last" :"Hazell"}, "sales" : "$2746", "branch": "New York City, NY"}, 
     {"name": {"first": "Homer", "last" :"Hirth"}, "sales" : "$474", "branch": "Orlando, FL"}, 
     {"name": {"first": "Hwa", "last" :"Heidt"}, "sales" : "$9607", "branch": "San Francisco, CA"}, 
     {"name": {"first": "Hyon", "last" :"Hampshire"}, "sales" : "$13598", "branch": "New York City, NY"}, 
     {"name": {"first": "Issac", "last" :"Ingerson"}, "sales" : "$5225", "branch": "Austin, TX"}, 
     {"name": {"first": "Jeraldine", "last" :"Joplin"}, "sales" : "$2891", "branch": "New York City, NY"}, 
     {"name": {"first": "Jin", "last" :"Jeffrey"}, "sales" : "$14402", "branch": "Austin, TX"}, 
     {"name": {"first": "Joleen", "last" :"Jolin"}, "sales" : "$15736", "branch": "Austin, TX"}, 
     {"name": {"first": "Jude", "last" :"Jarrett"}, "sales" : "$7557", "branch": "San Francisco, CA"}, 
     {"name": {"first": "Magda", "last" :"Mireles"}, "sales" : "$1498", "branch": "Austin, TX"}, 
     {"name": {"first": "Mistie", "last" :"Montealegre"}, "sales" : "$6920", "branch": "New York City, NY"}, 
     {"name": {"first": "Nancy", "last" :"Napoli"}, "sales" : "$5255", "branch": "New York City, NY"}, 
     {"name": {"first": "Regine", "last" :"Rohrbaugh"}, "sales" : "$7881", "branch": "Orlando, FL"}, 
     {"name": {"first": "Rolando", "last" :"Riebel"}, "sales" : "$8573", "branch": "San Francisco, CA"}, 
     {"name": {"first": "Scarlett", "last" :"Stagg"}, "sales" : "$7126", "branch": "Orlando, FL"}, 
     {"name": {"first": "Sherron", "last" :"Strawn"}, "sales" : "$8848", "branch": "New York City, NY"}, 
     {"name": {"first": "Susan", "last" :"Shilling"}, "sales" : "$8542", "branch": "Seattle, WA"}, 
     {"name": {"first": "Tama", "last" :"Tworek"}, "sales" : "$9200", "branch": "Seattle, WA"}, 
     {"name": {"first": "Tonisha", "last" :"Taunton"}, "sales" : "$5219", "branch": "Orlando, FL"}, 
     {"name": {"first": "Vergie", "last" :"Villescas"}, "sales" : "$8712", "branch": "New York City, NY"} 
    ]; 

    function convertSalesToInt(person){ 
     var salesInt = person.sales.slice(1); 
     return parseInt(salesInt, 10); 
    } 

    function salesPerBranch(salesPersons){ 
    var myObj = {}; 
    var uniq = []; 
    var total = 0; 

    for(var i = 0; i < salesPersons.length; i++){ 
     var splitTeam = salesPersons[i].branch; 
     if(uniq.indexOf(salesPersons) < 0){ 
     myObj[salesPersons] = total+= convertSalesToInt(salesPersons[i]); 
     } 
    } 

    return myObj; 


    } 

    console.log(salesPerBranch(salesPersons)); 
    /* { 'Austin, TX': 110898, 
    'New York City, NY': 187174, 
    'Orlando, FL': 178462, 
    'San Francisco, CA': 139527, 
    'Seattle, WA': 173243 } */ 

答えは次のようになります。私は今、立ち往生しています

{ 
    'Austin, TX': 48423, 
    'New York City, NY': 74572, 
    'Orlando, FL': 20700, 
    'San Francisco, CA': 25737, 
    'Seattle, WA': 17742 
} 

部分だけは、私は、各支店の総売上を追加する部分です。今、それは正しい量を引き上げていません。この部分はそれに責任があります：

私の間違いを知っていて、どうすればいいですか？

ありがとうございます！

    } 
 

 
    return myObj; 
 
} 
 

 
console.log(salesPerBranch(salesPersons));

あなたは、あなたがそれに追加している場合は、売上高がゼロにする、データをカウントしていないかどうかを確認する必要があります。

Answer 2

@ Durgaの答えに触発されたやや異なる方法があります。彼の答えを理解するためにfor ... ofループとif文を単純化しました。

function salesPerBranch(salesPersons) { 
     var myObj = {}; 

     //loop through sales people 
     for (let person of salesPersons) { 
     let branch = person.branch; 

     //test for branches 
     if (!myObj[branch]) { 
      //create branches in the obj 
      myObj[branch] = myObj[branch] 
      //set default value to 0 
      myObj[branch] = 0; 

     } 
     //Add sales for each branch 
     myObj[branch] += convertSalesToInt(person); 

     } 
     console.log(myObj) 

    } 

    salesPerBranch(salesPersons); 

Answer 3

これはトリック

salesPersons.map(function(x){return x.branch}).filter(function(value, index, self){return self.indexOf(value) === index;}).forEach(function(x){ 
     console.log(x + ' : $' + salesPersons.filter(function(y){if(y.branch === x) return y}).map(function(z){return z.sales.slice(1)}).reduce(function(a,b){return +a + +b;},0)); 
    });
