What's the easiest way to average an array of integers in javascript? -


if if have multiple arrays such as

[100, 43, 76, 95, 62], [27, 54, 99, 13, 56], [56, 92, 01, 46, 87]

what easiest way 1 array average of of each index? have dynamic number of arrays 6 items in each.

(for example average arrays above [61, 63, 59, 51, 68]

you need 1 loop elements same index of 3 arrays , calculate average:

var arr1 = [100, 43, 76, 95, 62];  var arr2 = [27, 54, 99, 13, 56];  var arr3 = [56, 92, 01, 46, 87];  var res = [];  for(var i=0; i<arr1.length; i++){    var avg = math.round((arr1[i]+ arr2[i]+ arr3[i])/3)    res.push(avg);  }    console.log(res);

and if have dymanic number of arrays works charm,

var data = [[100, 43, 76, 95, 62],[27, 54, 99, 13, 56],[56, 92, 01, 46, 87]];  var res = [], sum;  for(var i=0; i<data[0].length; i++){    sum = 0;    for(var j=0; j<data.length; j++){       sum+= data[j][i];    }    res.push(math.round(sum/data.length));  }  console.log(res);
