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

This question was posed to me in an international level competition.

This is a very interesting question from Comparison of Core JavaScript versus Frameworks in division Caching, Debugging and Animation of JavaScript

Answer 1

Correct choice is (d) timestamp.firstChild

To elaborate: The firstChild property returns the first child node of the specified node, as a Node object. The first child of a node can be accessed using the firstChild property.
