The Big Picture
create a small program that illustrates the IPO structure and other fundamental programming concepts
to reuse most of the same concepts to create a similar program, but with some modifications
we're going to learn how to skip some part of the code based on the input value
We can use another loop to repeat the entire program so the user can keep using the program without restarting it.
Problem Solving Patterns
In this chapter we'll look at a few common coding problems and their solutions.
Most functions that programmers use are either created by themselves or created by other programmers.
In this chapter, we're going to replace alert and prompt with a few common HTML elements
We'll use a very popular library called jQuery. It can help us to write more concise event handling code.
