Answer 2

Answer:

var salaries = new Array(69435, 59839,90729)

Explanation:

var salaries = new Array(69435, 59839,90729) Is the correct option..

An object known as an array may be used to hold a collection of items. Arrays are tremendously useful when you need to store a lot of the same kind of data in one location.

Say you want to maintain records for 500 workers. If you utilise variables, you would need 500 variables to do the same work as a single array.

You may access the elements of an array by using the index number of the array; the index of an array's first member is zero.

Developers can quickly and efficiently deal with arrays because to the Array object's numerous characteristics and methods.
