g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.

Answer and Explanation:

function processNumbers(alist){

var Ourarray= new array(alist);

Ourarray.foreach(

if(isNaN()){

Console.log( "An element in the list is not a number."};

break;

}

}

processNumbers(alist)

From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.
