0.1.3 • Public • Published

reduce-object NPM version

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:

npm i reduce-object --save

Run tests

npm test

Usage

Executes the callback function 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.
var reduce = require('reduce-object');
 
var a = {a: 'foo', b: 'bar', c: {}};
 
var obj = reduce(a, function (acc, value, key, orig) {
  if (typeof value === 'object') {
    acc[key] = {what: 'huh?'};
  } else {
    acc[key] = value.toUpperCase(); // why?
  }
  return acc;
}, {});
 
console.log(obj);
//=> {a: 'FOO', b: 'BAR', c: {what: 'huh?'}};
