Question

Which of the following key property holds the key name as a string?

(a) keyName

(b) key

(c) keyName(string)

(d) Nameofkey(string)

The question was posed to me in an interview for internship.

My question is taken from Keyboard Events in portion Document Object Model and Event Handling in Javascript of JavaScript

Answer 1

Correct option is (b) key

To elaborate: The DOM Level 3 Events defines a new key property that contains the key name as a string. Object.keys() returns an array whose elements are strings corresponding to the enumerable properties found directly upon object.
