Answer:
- function processNumbers(numList){
- try{
- for(let i=0; i < numList.length; i++){
- if(isNaN(numList[i])){
- throw "All elements in the list should be numbers.";
- }
-
- }
- }
- catch(err){
- console.log(err);
- }
- }
-
- let myList = [4, 6, 1, "abc", 9];
- processNumbers(myList);
Explanation:
The solution code is written in JavaScript as the isNaN() is an in-built function in JavaScript.
Firstly, create a function processNumbers that takes one input number list, numList (Line 1).
To handle the possible Not a Number (NaN) error, create a try and catch block. In the try block, create a for-loop to traverse through the numList array and use isNaN function to check if the current value is a number (Line 3 - 4). If it is not a number, isNaN will return true and the program will run the throw statement (Line 5). The throw message will be passed to the catch block and display it on console (Line 10 - 12).
We can test the function by using the sample list (Line 15 - 16) and we shall see the thrown error message is displayed.

For security and privacy reasons, it is best to use the Blind Carbon Copy (BCC) feature when sending an email message to a large number of people. When you place email addresses in the BCC field of a message, those addresses are invisible to the recipients of the email.
Explanation:
<u>Swap files </u>contain(s) remnants of word processing documents, e-mails, Internet browsing activity, database entries, and almost any other work that has occurred during past Windows sessions.
Explanation:
I order to simulate extra space an operating system like windows use hard disk space in order to stimulate extra memory.When a computer system is running low with the memory space the swap file swaps a section of RAM onto the hard disk in order to obtain a free memory space.
This Process at times results in slowing down of the computer computer considerably.
<u>The combination of RAM and swap files is known as virtual memory.</u>
It is due to the use of virtual memory that our computer is able to run more programs than it could run in RAM alone.
