foreach-object

This library provides secure foreach functionality for objects. Mainly focuses on avoiding some common errors that encounter with javascript for-in iterations, such as iterating through prototype properties.

Method signature is similar to Array.prototype.forEach.

Installation

npm i foreach-object

Example Usage

After installing foreach-object module, you can use either import syntax of ES6 or require syntax of node to make this library available in your file.

Using import

import each from 'foreach-object';
   
const object = {
   firstName: 'Arosha',
   lastName: 'Sum',
   country: 'Australia'
};
   
each(object, (value, key, object) => {
   console.log(key + ': ' + value);
});
   
// Console log output will be:
//      firstName: Arosha
//      lastName: Sum
//      country: Australia

Using require

const each = require('foreach-object');

const object = {
   firstName: 'Arosha',
   lastName: 'Sum',
   country: 'Australia'
};
   
each(object, (value, key, object) => {
   console.log(key + ': ' + value);
});
   
// Console log output will be:
//      firstName: Arosha
//      lastName: Sum
//      country: Australia

Remarks

This library will iterate through object's own properties only. Therefore, prototype properties will be ignored.
