For this lab we would like you to complete the following exercises in CoffeeScript. You can do this in a Rails app or in a seperate coffee file.

Define a function reverse() that reverses a string. For example, reverse("building") should return the string "gnidliub".

Write a function filterLongWords() that takes an array of words and an integer i and returns an array of words that are longer than i.

Write a function range that takes one argument, a positive number, and returns an array containing all numbers from 0 up to and including the given number.

Write a function called startsWith that takes two arguments, both strings. It returns true when the first argument starts with the characters in the second argument, and false otherwise.

Write a function named assignGrade that:

• takes 1 argument, a number score.
• returns a grade for the score, either "A", "B", "C", "D", or "F".

Call that function for a few different scores and log the result to make sure it works.

Write a function named pluralize that:

• takes 2 arguments, a noun and a number.
• returns the number and pluralized form, like "5 cats" or "1 dog".

Call that function for a few different scores and log the result to make sure it works.

Store a celsius temperature into a variable. Convert it to fahrenheit and output "NN°C is NN°F".
