Introduction to JavaScript: First Steps

# Types of Variables

There are a few different types of variables in JavaScript. We'll discuss **numbers**, **strings**, and **booleans** first.

# Numbers

Numbers are just what you'd expect and what we've been using in the examples above. `19`, `30`, `924311933` are all numbers. We can't use commas, spaces, or other characters when we create numbers. We have to use continuous digits.

# Strings

Strings are different. We can think of them as the way we represent text in JavaScript. They're created using the `'` and `"` characters. For example, if we wanted to store a representation of the word `Hello` in JavaScript, we could write it two different ways.
