linusu / object-map

map a function over some Object's values to produce a new Object

Map a function over the values of an Object to produce a new Object with the same keys.

The API is modelled after the native Array#map method.

Installation

$ npm install --save object-map

Example

var objectMap = require('object-map');

var target = {
  foo: 1,
  bar: 2
};

var result = objectMap(target, function(value) {
  return value * value;
});
// => {foo: 1, bar: 4}

API

objectMap(target, callback[, thisArg])

• target an object who's properties are iterated using hasOwnProperty
• callback a function producing a value of the new Object, taking three arguments:
  • currentValue the value currently associated with the key
  • key the current key
  • object the original object passed to objectMap
• thisArg Optional. Value to use as this when executing callback.
