object.map NPM version NPM monthly downloads NPM total downloads Linux Build Status Windows Build Status

Similar to map for arrays, this creates a new object by calling the callback on each property of the original object.

Install

Install with npm:

$ npm install --save object.map

Usage

var mapValues = require('object.map');

var result = mapValues({a: 'a', b: 'b'}, function(val, key, obj) {
  return val + val;
});
console.log(result);
//=> {a: 'aa', b: 'bb'}

Optionally specify a thisArg as the last argument:

var result = mapValues({a: 'b'}, function(val, key, obj) {
  return this.foo;
}, {foo: 'bar'});
console.log(result);
//=> {a: 'bar'}
