How does lodash.isPlainObject work?

lodash.isPlainObject is a function in the Lodash library that checks if a given value is a plain object, meaning it was created with the object literal syntax {} or with the Object constructor and does not inherit from a prototype other than Object.prototype. The function returns true if the value is a plain object and false otherwise. It also returns false for null and non-object values. The function performs this check by verifying that the value is an object and that its prototype is either null or Object.prototype.

// FIXME: We don't want empty objects to be added to the resulting JSON.
// This is the default behaviour of Bookshelf when using single entities,
// but for collections it isn't. Looks like a bug in their side (see
// https://github.com/tgriesser/bookshelf/issues/753)
const isEmptyPlainObject = (value) => _.isPlainObject(value) && _.isEmpty(value);

// FIXME: This is a workaround because Swagger doesn't allow nullable
// fields. Check https://github.com/OAI/OpenAPI-Specification/issues/229.
const isNullOrEmptyPlainObject = (value) => (value === null) || isEmptyPlainObject(value);

const _ = require("lodash");

const obj = { a: 1, b: 2 };
const arr = [1, 2, 3];
const func = () => {};

console.log(_.isPlainObject(obj)); // true
console.log(_.isPlainObject(arr)); // false
console.log(_.isPlainObject(func)); // false

In this example, we import the lodash library and create an object, array, and function. We then use the _.isPlainObject() method to check whether each of these values is a plain object. As expected, obj returns true, while arr and func return false.
