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.
Answer:
No, this is not possible. Due to low bandwidth, neither video nor teleconferencing will be possible. Moreover, large size study materials will take quite a while to be downloaded and uploaded. And hence, it will be very difficult to ensure distance learning online as student-student, and student-teacher as well as teacher-teacher, and management-teacher-student interaction will be very difficult.

Answer:
"use the span element to create logical areas on a web page that are embedded within paragraphs or other block formatting elements."
Explanation:
- The question is associated with HTML and web pages. As span is a type of function in HTML.
- <span> element is actually a generic in-line tool/container which is used for content phrasing. Its functionality is much like a <div> element but <div> is a block-level element and on the other hand <span> element is in-line element.
- <span> element groups elements for styling purposes, but it does not represents anything inherently.
