What are lodash.forin's main functionalities?

Iterate over object properties

This feature allows you to iterate over all enumerable properties of an object, including inherited properties. The provided function is invoked for each property.

const forIn = require('lodash.forin');

const object = { 'a': 1, 'b': 2, 'c': 3 };

forIn(object, function(value, key) {
  console.log(key, value);
});

Other packages similar to lodash.forin

for-own

The for-own package is a utility for iterating over the own enumerable properties of an object. Unlike lodash.forin, it does not iterate over inherited properties, making it more focused on the object's own properties.

object.entries

The object.entries package provides a method to return an array of a given object's own enumerable string-keyed property [key, value] pairs. It is a part of the ECMAScript 2017 standard and does not include inherited properties, similar to for-own.
