Exercise Weekend

Goal: In the Variables lesson, we learned:

• Variables, in JavaScript, are written in lower camelcase
• Variables are set using `let` and `const`
• Variables can be used in arithmetic

Practice creating and utilizing variables by completing the exercises listed below. Variables are a fundamental building block of programming; so begin getting comfortable with them now!

## Warm Up

• When are `let` and `const` used? What do they mean - and how are they different from `var`?
• How can we use a variable after we've defined it?

## Code

### Variables Practice

Here are a few exercises for you to practice using variables:

• Set a variable called `someName` equal to your name. Put your name in quotation marks.
• Display the value of `someName` in the console.
• Change the value of `someName`.
• Set a variable called `favoriteNumber` equal to your favorite number.
• Calculate what your favorite number divided by 2 is.
• Set another variable called `michaelsFavorite` equal to `13`.
• Change the value of `michaelsFavorite` to `7`.
• Subtract your favorite number from mine.
• Change the value of my favorite number to be 26 times its current value.
