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

Package Exports

  • object.map

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (object.map) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Install

Install with npm:

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'}
