javascript - How to swap several objects values? -


for example have 2 objects same keys:

var = {     k1: "aa",      k2: "ab",      k3: "ac",      k4: "ad",     k5: "ae"         } var b = {     k1: "ba",      k2: "bb",      k3: "bc",      k4: "bd",     k5: "be"         }

for example, need swap values k2, k3, k4 between these objects. so, want result:

a = {     k1: "aa",      k2: "bb",      k3: "bc",      k4: "bd",     k5: "ae"         } b = {     k1: "ba",      k2: "ab",      k3: "ac",      k4: "ad",     k5: "be"         }

is there way fast? believe can performed without adding intermediate object.

simple solution using object.keys() , array.prototype.indexof() functions:

var = {k1: "aa",k2: "ab",k3: "ac",k4: "ad",k5: "ae"},      b = {k1: "ba",k2: "bb",k3: "bc",k4: "bd",k5: "be"},      swapkeys = ['k2', 'k3', 'k4'];    swapkeys.foreach(function (k) {      if (k in && k in b) {          var values = [a[k], b[k]];          a[k] = values[1];          b[k] = values[0];      }  });    console.log(a);  console.log(b);

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
