What will be the result of executing console.log(arr.slice(1, 3)) for arr being [1, 4, 9, 16]?

The result of executing console.log(arr.slice(1, 3)) when arr is set to [1, 4, 9, 16] is indeed [4, 9]. The slice method in JavaScript is used to create a shallow copy of a portion of an array into a new array object, selecting elements starting from the index defined by the first argument (inclusive) up to, but not including, the index defined by the second argument (exclusive).

In this case, calling arr.slice(1, 3) begins at index 1, which corresponds to the value 4, and continues up to index 3, which corresponds to the value 16. The values returned are only those at indices 1 and 2. Specifically:

• Index 1 has the value 4.

• Index 2 has the value 9.

Thus, the resulting array will contain the elements [4, 9], which is consistent with the correct answer provided. This demonstrates how the slice method operates within the context of JavaScript array manipulation.
