JavaScript Fundamentals 3 - Declaring and initializing arrays

31.

Which of the following correctly declares and initializes an array in JavaScript?

var arr = ();

var arr = 5;

var arr = [1, 2, 3];

var arr = "apple";

Correct: C

In JavaScript, arrays can be declared and initialized using square brackets [ ]. Option 3 correctly initializes an array with three elements: 1, 2, and 3. The other options are incorrect because they do not follow the correct syntax for declaring and initializing arrays.
