What is @stdlib/utils-get-prototype-of?

@stdlib/utils-get-prototype-of is a utility package that provides a function to get the prototype of an object. This can be useful in various scenarios such as inheritance checks, debugging, and understanding object structures.

What are @stdlib/utils-get-prototype-of's main functionalities?

Get Prototype of an Object

This feature allows you to retrieve the prototype of a given object. In this example, the prototype of an empty object is retrieved and logged to the console.

const getPrototypeOf = require('@stdlib/utils-get-prototype-of');
const obj = {};
const proto = getPrototypeOf(obj);
console.log(proto);

Check Inheritance

This feature can be used to check if an object inherits from a specific prototype. In this example, we create a parent and child constructor, set up inheritance, and then check if an instance of the child inherits from the parent's prototype.

const getPrototypeOf = require('@stdlib/utils-get-prototype-of');
function Parent() {}
function Child() {}
Child.prototype = Object.create(Parent.prototype);
const childInstance = new Child();
const isInherited = getPrototypeOf(childInstance) === Parent.prototype;
console.log(isInherited);
