# object.reduce [![NPM version](https://img.shields.io/npm/v/object.reduce.svg?style=flat)](https://www.npmjs.com/package/object.reduce) [![NPM monthly downloads](https://img.shields.io/npm/dm/object.reduce.svg?style=flat)](https://npmjs.org/package/object.reduce) [![Linux Build Status](https://img.shields.io/travis/jonschlinkert/object.reduce.svg?style=flat&label=Travis)](https://travis-ci.org/jonschlinkert/object.reduce) > Reduces an object to a value that is the accumulated result of running each property in the object through a callback. ## Install Install with [npm](https://www.npmjs.com/): ```sh $ npm install --save object.reduce ``` Install with [yarn](https://yarnpkg.com): ```sh $ yarn add object.reduce ``` Install with [bower](https://bower.io/) ```sh $ bower install object.reduce --save ``` ## Usage the initial value (or value from the previous callback call), the `value` of the current property, the `key` of the current property, and the `object` over which the function is iterating. Node.js/JavaScript utility.)_ **Params** * `object` **{Object}**: The object to iterate over (the iteratee) * `fn` **{Function}**: The function invoked per iteration. * `init` **{Object}**: The initial value to use for the accumulator. * `thisArg` **{Object}**: (optional) Object to use as the invocation context for the iterator (expose as `this` inside the iterator) Executes the given callback `fn` once for each own enumerable property in the object. The callback receives the following arguments: * `acc`: the initial value (or value from the previous callback call), * `value`: the of the current property, * `key`: the of the current property, and * the original `object` over which the function is iterating. **Example** ```js var reduce = require('object.reduce'); var a = {a: 'foo', b: 'bar', c: 'baz'}; reduce(a, function(acc, value, key, obj) { acc[key] = value.toUpperCase(); return acc; }, {}); //=> {a: 'FOO', b: 'BAR', c: 'BAZ'}; ``` ## About ### Contributing Pull requests and stars are always welcome.
