javascript - Array creating using specific property of array of objects -


this question has answer here:

there array of objects follows. need create array using vatcode propery following array of objects without going through 'for loop'. here result should be
resultarray = [1, 15, 25]

"data": [     {         "id": 1,         "vatcode": 1,         "name": "ingen mva.",                     "vataccount": {             "id": 3,             "accountno": "3190",             "name": "misc items income"         }                 },     {         "id": 2,         "vatcode": 15,         "name": "lav mva.",                    "vataccount": {             "id": 3,             "accountno": "3190",             "name": "misc items income"         }     },     {         "id": 3,         "vatcode": 25,         "name": "høy mva.",                    "vataccount": {             "id": 3,             "accountno": "3190",             "name": "misc items income"         }     },  ] 

data = //your json data      this.data.map(data => data.vatcode);

the map() method creates new array results of calling function every array element.

var data = [      {          "id": 1,          "vatcode": 1,          "name": "ingen mva.",                      "vataccount": {              "id": 3,              "accountno": "3190",              "name": "misc items income"          }                  },      {          "id": 2,          "vatcode": 15,          "name": "lav mva.",                     "vataccount": {              "id": 3,              "accountno": "3190",              "name": "misc items income"          }      },      {          "id": 3,          "vatcode": 25,          "name": "høy mva.",                     "vataccount": {              "id": 3,              "accountno": "3190",              "name": "misc items income"          }      },    ];    var s = data.map(data => data.vatcode);  console.log(s);

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
