## Strings
|
||
|
|
|
||
|
|
Strings in Elixir are wrapped with double-quotes, while Character Lists are single-quoted. They are UTF-8 encoded binaries.
|
||
|
|
```elixir
|
||
|
|
iex> "Hello world!"
|
||
|
|
"Hello world!"
|
||
|
|
```
|
||
|
|
|
||
|
|
String Interpolation is possible in Elixir with an octothorp followed by curly braces.
|
||
|
|
```elixir
|
||
|
|
iex> variable = "world!"
|
||
|
|
"world!"
|
||
|
|
iex> "Hello #{variable}"
|
||
|
|
"Hello world!"
|
||
|
|
```
|
||
|
|
|
||
|
|
The String module contains many helpful built in functions based on the Unicode standard.
|
||
|
|
```elixir
|
||
|
|
iex> example = "string"
|
||
|
|
"string"
|
||
|
|
iex> String.capitalize(example)
|
||
|
|
"String"
|
||
|
|
iex> String.duplicate(example, 2)
|
||
|
|
"stringstring"
|
||
|
|
```
