JS Interview Question: What’s the difference between host objects and native objects?
What’s the difference between host objects and native objects?
From what I understand, objects are divided from which environment and language they are supplied: Host Objects and Native Objects.
Host Objects are objects supplied by a certain environment. They are not always the same because each environment differs and contains host objects that accommodates execution of ECMAScript. Example, browser environment supplies objects such as window. While a node.js/server environment supplies objects such as NodeList.
Native Objects or Built-in Objects are standard built-in objects provided by Javascript. Native objects is sometimes referred to as ‘Global Objects’ since they are objects Javascript has provided natively available for use.
There are various articles categorizing these native global objects but its number differs, so for accuracy (I believe), I recommend the official Mozilla Doc as reference. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects
Javascript is mainly constructed by these categorized native global objects. These objects can be used either as Constructor (String(), Number(), Boolean()) or as Primitive Value, like literally as a value :-D (‘string’, 123, true).
