Answer 1

Why do you expect mynewArray to work ? Did you created a constructor function for it since you are created an new object for it(mynewArray) ,to declare a array you need to use the built in Array() constructor for creating array objects

I think you should go through some tutorials online and through the course in here as well to understand how to work with arrays

Answer 4

Avinash to declare a array you should call Array instead of myNewArray.
And a typo in the last line :
document.write(myArray1[i][j + "&emsp"]);

In this line you are trying to access myArray1's i th row's j+"&emsp" th value (which always returns undefined).
You may be trying to add   char at the end of each number in the array. If so then it should be document.write(myArray1[i][j]+ " "); (also an html character code should begin with an '&' and end with ';').
Corrected code :
