## Usage

```javascript
var reinterpret = require( '@stdlib/strided/base/reinterpret-boolean' );
```

#### reinterpret( x, offset )

Returns a [`Uint8Array`][@stdlib/array/uint8] view of a [`BooleanArray`][@stdlib/array/bool].

```javascript
var BooleanArray = require( '@stdlib/array/bool' );

var x = new BooleanArray( 10 );

var view = reinterpret( x, 0 );
// returns <Uint8Array>

var bool = ( view.buffer === x.buffer );
// returns true

var len = view.length;
// returns 10
```

The `offset` argument specifies the starting index of the returned [`Uint8Array`][@stdlib/array/uint8] view relative to the [`BooleanArray`][@stdlib/array/bool].

```javascript
var BooleanArray = require( '@stdlib/array/bool' );

var x = new BooleanArray( [ true, false, false, true, true, false ] );

var view = reinterpret( x, 2 );
// returns <Uint8Array>

var len = view.length;
// returns 4

var v = view[ 0 ];
// returns 0

v = view[ 1 ];
// returns 1
```

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var BooleanArray = require( '@stdlib/array/bool' );
var reinterpret = require( '@stdlib/strided/base/reinterpret-boolean' );

// Define a boolean array:
var x = new BooleanArray( [ true, false, false, true, true, false ] );
// returns <BooleanArray>

// Reinterpret as a `uint8` array:
var view = reinterpret( x, 0 );
// returns <Uint8Array>

// Set view elements:
view[ 0 ] = 0;
view[ 1 ] = 1;

// Get the first element of the boolean array:
var v = x.get( 0 );
// returns false

// Get the second element of the boolean array:
v = x.get( 1 );
// returns true
```
