Add specific values of multidimensional array together Javascript -


okay, have multidimensional array contains 9 arrays. each of these nested arrays contains 10 numeric values. sake of simplicity, let's looks this:

var myarray = [ [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10] ]

i trying write function take first index of each nested array (in case, 1's) , add them together, pushing value either array or object. then, need function continue on, adding values of next index, , next, , on , forth. in end, should have array of 10 values (or object works here well). values be:

1+1+1+1+1+1+1+1+1, 2+2+2+2+2+2+2+2+2, 3+3+3+3+3+3+3+3+3...

...and on forth, actual values of new array this:

[9, 18, 27, 36, 45, 54, 63, 72, 81]

the catch here need flexible/dynamic, work in case myarray has 6 arrays, or maybe nested arrays have 4 values each. should work amount of nested arrays, each own amount of values (though each nested array contain same amount of values 1 another!).

what best way accomplish via javascript and/or jquery? note have values output object, in fashion:

{1:9, 2:18, 3:27, 4:36, 5:45, 6:54, 7:63, 8:72, 9:81}

i tried using similar code stackoverflow thread object, returning

{1:nan, 2:nan, 3:nan, etc.}

that thread can found here:

javascript multidimensional array: add values

i'm using "underscore" method , jquery $.each part of provided otto.

anyone able here??

here solution:

var myarray = [ [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10], [1,2,3,4,5,6,7,8,9,10] ]  var results= [];  myarray.map(function(a){     for(var i=0;i<a.length;i++){         if(results.length === a.length){             results[i] = results[i] + a[i];         }else{             results.push(a[i]);         }     } });

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
