Empty arrays and lists can be useful for storing values temporarily before adding them to the array or after removing them from the list. they can also be used as placeholders when you don't know how many values you need but know that they will all be different. In javascript, arrays are a fundamental data structure commonly used to store and manage collections of elements. in interviews or practical scenarios, a common question might be: “how can. An array in js is not necessarily given contiguous memory like with other languages, so a sparse array can definitely have the empty slots not even taking up space. null and undefined are both values, so they are something that exists. Since your array is defined to be global, you can access it within the function. you do not need to iterate over the array, and you can simply use the .push() method to easily append a string to your array.
