javascript - merge array on keys -


sorry if duplicate, can't find suitable answer. have 2 arrays:

array1 = { '0': 'f1', '1': 'f2'}; array2 = { '0': 's1', '1': 's2'};

how combine (merge) these 2 arrays this:

array3 = [['f1', 's1'], ['f2', 's2']];

thanks!

if inputs arrays

var = ['f1', 'f2']; var b = ['s1', 's2'];

the transformation looking zip

var zip = (xs,ys)=>   xs.reduce((zs,x,i)=>     zs.concat([[x, ys[i]]]), []);  zip(a,b); //=> [['f1', 's1'], ['f2', 's2']]

this assumes both inputs same length.

if inputs objects numerical keys

var = {'0': 'f1', '1': 'f2'}; var b = {'0': 's1', '1': 's2'};  var zipobj = (xs,ys)=>   object.keys(xs).reduce((zs,xk)=>     zs.concat([[xs[xk], ys[xk]]]), []);  zipobj(a,b); //=> [['f1', 's1'], ['f2', 's2']]

despite not having asked it, oblige trey i've included es5 versions of functions

"use strict";  // zip arrays var zip = (xs,ys)=>   xs.reduce((zs,x,i)=>     zs.concat([[x, ys[i]]]), []);  // zip objects var zipobj = (xs,ys)=>   object.keys(xs).reduce((zs,xk)=>     zs.concat([[xs[xk], ys[xk]]]), []);

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
