How does lodash.toPlainObject work?

lodash.toPlainObject creates a plain object from an object that is inherited from a prototype. It creates a new object with its own properties only and not the inherited ones. If the object is already a plain object with no inherited properties, it returns the object itself. Internally, lodash.toPlainObject uses Object.create(null) method to create a new object with no prototype, hence it doesn't inherit any properties from the prototype chain. It then copies all the own enumerable string keyed properties from the original object to the newly created plain object. This ensures that the returned object has only its own properties and doesn't contain any properties inherited from its prototype chain.

const obj = Object.create({ foo: 1 });
obj.bar = 2;

const plainObj = _.toPlainObject(obj);

console.log(plainObj); // { bar: 2 }

In this example, lodash.toPlainObject is used to create a plain object from the given object obj. obj is created using Object.create() and has a property bar with the value 2. When lodash.toPlainObject is called with obj as the argument, it returns a new object with the same properties and values as obj, but without the foo property inherited from the prototype. Finally, the resulting plain object is logged to the console.
