# concat

> Concatenates all of the strings passed in as arguments together.

**This function is used by Ignition's Expression language.**

## Description

## Syntax
`concat(string, [string, ...])`

### Parameters

| Type | Parameter | Description |
|---|---|---|
| String | `string` | Any number of string values to concatenate together. |

### Results
**String** - A string that is all of the strings provided concatenated together.

## Examples
```python title="Code Snippet"
concat("The answer is: ", "42") //returns "The answer is: 42"
```
