Iterate over the enumerable properties of an object, and return an object with properties that evaluate to true from the callback. Exit early by returning `false`.

Package Exports

  • for-in

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 (for-in) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

for-in NPM version

Returns true if an object has any of the specified keys.

Install

Install with npm:

npm i for-in --save

Run tests

npm test

Usage

var forIn = require('for-in');

var obj = {a: 'foo', b: 'bar', c: 'baz'};
var values = [];
var keys = [];

forIn(obj, function (value, key, o) {
  keys.push(key);
  values.push(value);
});

console.log(keys);
//=> ['a', 'b', 'c'];

console.log(values);
//=> ['foo', 'bar', 'baz'];
