# ISSTRING

**The function ISSTRING outputs TRUE if the given input is a string.**

This function takes any variable type as input. It then checks to see if the input is a [string](../../variable-data-types/the-text-variable-data-type) and outputs **TRUE** if it is, **FALSE** if it isn't.

#### Declaration

```javascript
ISSTRING(value) -> result
```

&#x20;

#### Parameters

**value** (required, type: _any_) A value that may or may not be a string.

#### Return Values

**result** (type: _boolean_) The result of checking if the given string is a string; **TRUE** means that it is and **FALSE** means that it isn't.

### Examples

The following example confirms that the string "Hello, world!" is a string:

```javascript
ISSTRING("Hello, world!") => TRUE
```

The following example takes the Number 3 and returns **FALSE** because 3 is a Number, not a string:

```javascript
ISSTRING(3) => FALSE
```
