What's a Hash and why is it important?

A Hash is a collection of key-value pairs. To add, fetch, modify, and delete a value from a Hash, you refer to it with a unique key.

While an Array is indexed by Integers only, a Hash is keyed by any object -- Strings, Integers, etc.

In other programming languages, a Hash might be known as an 'associative array', 'dictionary', or 'HashMap'.

What does a Hash look like?

Good etiquette in class can help you make the most of your education.

You're an adult; act like one.

If you're in Code Fellows, you're likely at least 18 years old—the age at which you're legally considered an adult. You may not feel like a responsible grown-up yet, but your instructors will assume that you are. So act likewise.

Before you say or do anything in the classroom, ask yourself "How would a mature, well-adjusted, courteous adult act?" I promise that doing so will save you from embarrassment and engender the respect of your classmates and instructors.

Present yourself well.
