Question

A linkage of series of prototype objects is called as ________

(a) prototype stack

(b) prototype chain

(c) prototype class

(d) prototypes

I had been asked this question in a job interview.

Origin of the question is Object Attributes and Serialization in chapter Lexical Structures of JavaScript

Answer 1

Right option is (b) prototype chain

Easy explanation: Consider an example, Date.prototype inherits properties from Object.prototype, so a Date object created by new Date() inherits properties from both Date.prototype and Object.prototype. This linked series of prototype objects is known as prototype chain.
