Introduction to JavaScript: First Steps

Let's introduce some logical operators to make if-statements more powerful.

## `!`

The `!` operator is called the "not"-operator. It does two things to a value: it coerces it to either `true` or `false`, and then gives the *opposite* value. Falsey values become `true` and truthy values become `false`.

For example, `!true` will become `false`. `!0` will become `true`. `!''` will become `true`. Think of this operator as saying "This item is NOT true" or "This item is NOT false".

Learn operators that will make our conditional code much more interesting and powerful. Learn how to combine operators for more complex logic.
