Functions Exercises

Exercise 1

A club has the following members:

First name	Last name	Year joined
Jon	Snow	2000
Arya	Stark	2013
Tywin	Lannister	1987

1. Write a function that takes a first name, a last name and a joining year parameter, and returns a message as a string that congratulates a member for their membership anniversary. E.g. Jon Snow receives the message "Dear Jon Snow, thank you for being a member for 21 years!"
2. Add a comment above your function to explain what it does.
3. Call your function with each member of the club and log the results to the console.
4. What's the difference between a return and console.log?
5. When would you choose to use functions over the way we have been scripting so far?

Exercise 2

As a gift to long-term members, the club offers a 10% discount from the membership fee.

1. Write a function that takes a price parameter and returns the input price reduced by 10%.
2. Call your function with the annual membership fee of £100 and the monthly membership fee of £10 and log the results to the console.
3. How would you modify the function if the annual membership fee is reduced by 10% but the monthly membership fee is only reduced by 5%?
