Assignment 4: Expressions and Conditions: Part 1

  1. [2 pts] Create a page that asks a user first for their name, then for their favorite color, and then for their phone number and displays the results as a table in the page.
  2. [2 pts] Create a page that asks the user for two numbers (that is, asks twice for one number each time) and then displays the numbers and their sum, difference, product, quotient, and remainder as a table in the page.
  3. [2 pts] Create a page that asks the user for a number and reports whether or not the number is even. Hint: Think what it means to be even and check out the remainder operator (%).

Things to think about

  • Understand the difference between strings and numbers (even though Javascript converts many things to strings when necessary).
  • Understand that even though Javascript is a weakly (or loosely) typed language, nonetheless values are typed.
  • Check out the typeof operator which can be helpful in debugging type problems.

On to Part 2 when it is available...
