Strings are defined using the built-in `string` type like this:

<!--DOCUSAURUS_CODE_TABS-->
<!--Pascaligo-->
```
const a: string = "Hello Alice";
```
<!--CameLIGO-->
```
let a: string = "Hello Alice"
```
<!--ReasonLIGO-->
```reasonligo
let a: string = "Hello Alice";
```

## Concatenating strings

<!--DOCUSAURUS_CODE_TABS-->
<!--Pascaligo-->
Strings can be concatenated using the `^` operator.

```pascaligo
const name: string = "Alice";
const greeting: string = "Hello";
// Hello Alice
const full_greeting: string = greeting ^ " " ^ name;
// Hello Alice! (alternatively)
const full_greeting_exclamation: string = string_concat(full_greeting, "!");
```
<!--CameLIGO-->
Strings can be concatenated using the `^` operator.

```cameligo
let name: string = "Alice"
let greeting: string = "Hello"
let full_greeting: string = greeting ^ " " ^ name
```
<!--ReasonLIGO-->
Strings can be concatenated using the `++` operator.

```reasonligo
let name: string = "Alice";
let greeting: string = "Hello";
let full_greeting: string = greeting ++ " " ++ name;
```

## Slicing strings

Strings can be sliced using the syntax specific built-in built-in function:

<!--DOCUSAURUS_CODE_TABS-->
<!--Pascaligo-->
```pascaligo
const name: string = "Alice";
// slice = "A"
const slice: string = string_slice(0n, 1n, name);
```
<!--CameLIGO-->
```cameligo
let name: string = "Alice"
let slice: string = String.slice 0n 1n name
```
<!--ReasonLIGO-->
```reasonligo
let name: string = "Alice";
let slice: string = String.slice(0n, 1n, name);
```
<!--END_DOCUSAURUS_CODE_TABS-->

> ⚠️ Notice that the `offset` and slice `length` are `nats`

## Aquiring the length of a string

The length of a string can be found using the syntax specific built-in function:

<!--DOCUSAURUS_CODE_TABS-->
<!--Pascaligo-->
```pascaligo
const name: string = "Alice";
// length = 5
const length: nat = size(name);
```
<!--CameLIGO-->
```cameligo
let name: string = "Alice"
let length: nat = String.size name
```
<!--ReasonLIGO-->
```reasonligo
let name: string = "Alice";
let length: nat = String.size(name);
```
