# Hints
|
||
|
|
|
||
|
|
## General
|
||
|
|
|
||
|
|
- Read about `if` in the official [Getting Started guide][getting-started-if-unless] or on [elixirschool.com][elixirschool-if-unless].
|
||
|
|
|
||
|
|
## 1. Print a badge for an employee
|
||
|
|
|
||
|
|
- This is a base case where we can assume that none of the input data is `nil`.
|
||
|
|
- If you need to refresh your memory about working with strings, read about them in the official [Getting Started guide][getting-started-basic-strings].
|
||
|
|
|
||
|
|
## 2. Print a badge for a new employee
|
||
|
|
|
||
|
|
- Strings are always _truthy_ and `nil` is _falsy_.
|
||
|
|
- There is a [macro][kernel-if] that returns one of the two options, depending of whether it was given a _truthy_ or a _falsy_ value.
|
||
|
|
|
||
|
|
## 3. Print a badge for the owner
|
||
|
|
|
||
|
|
- Strings are always _truthy_ and `nil` is _falsy_.
|
||
|
|
- There is a [macro][kernel-if] that returns one of the two options, depending of whether it was given a _truthy_ or a _falsy_ value.
