HTF

• Find the exchange rate between dollars and pounds

Converting dollars to pounds:

• Store a dollar amount into a variable.
• Convert it to pounds and output "$NN is £NN".

Converting pounds to dollars:

• Now store a pound amount into a variable.
• Convert it to dollar and output "£NN is $NN."

Cleaning it up:

• Can you make sure the output is only 2 decimal places?

Refactoring

• Can you refactor the code so that it uses functions? Write a function dollarsToPounds that takes a dollar number as input and outputs a string of what the pound equivalent is.
• Do the same for poundsToDollars

This for That App

Students will build a "this for that" application that pulls words from array and combines them into strings

Objectives:

• create and use arrays
• create and use variables
• create and use functions

How to lead the lesson

Have you seen this website? It's the inspiration for this exercise. We're going to recreate a console version of this site. What does your startup do? Let's practice using arrays to find out!

• Write a function called randomThis() that picks a random "This" element from the array
• Write a function called randomThat() that picks a random "That" element from the array
• Write a function that prints a statement saying: "So.... your startup is basically like a like a this for that?" It should print a new statement each time the function is called.
