What is for-in?

The 'for-in' npm package is a utility that allows you to iterate over the properties of an object in JavaScript. It provides a simple and efficient way to loop through object keys, even for objects that inherit properties from their prototype.

What are for-in's main functionalities?

Iterating over object properties

This feature allows you to loop through each property of an object. The function provided to forIn is called with each property's value and key. This is particularly useful for objects with enumerable properties.

const forIn = require('for-in');
const object = {a: 1, b: 2, c: 3};
forIn(object, function(value, key) {
  console.log(key + ': ' + value);
});
