Question

What is the property to access the first child of a node?

(a) timestamp.Child1

(b) timestamp.Child(1)

(c) timestamp.Child(0)

(d) timestamp.firstChild

The question was asked during an online interview.

I'd like to ask this question from JavaScript in Web Browsers in chapter Server-Side and Client-Side Scripting of JavaScript

Answer 1

Correct answer is (d) timestamp.firstChild

The explanation is: The first child of a node can be accessed using the firstChild property. firstChild returns the first child node as an element node, a text node or a comment node (depending on which one’s first).
