extension: task 4

a) Building on the sketch you made in task 4.

Create a copy of t04_variables.js naming it t04_variables_ext.js

b) Create a program that does the following:

• • • Define two new variables named:

      • • stringVariable and set it to the string "eighteen"

        • numberVariable and set it to the number 18

    • Display the type of (use typeof statement) variable for each of your variables:

Sometimes your program fails due to a variable being a different data type than you expected.

EG; you expected a variable to be a numeric and could do math on it, however the math failed.

You can use the typeof command to help diagnose the problem.
