object.reduce

object.reduce

Reduces an object to a value that is the accumulated result of running each property in the object through a callback.

Executes the callback function once for each own enumerable property in the object, receiving four arguments: 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.

Install

Install with npm

npm i object.reduce --save

Install with bower

bower install object.reduce --save

Run tests

npm test

Usage

A callback function is executed once for each own enumerable property in the object, receiving four 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

var reduce = require('reduce-object');
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'};
