# Orders
> List of ndarray orders.
## Usage
```javascript
var orders = require( '@stdlib/ndarray/orders' );
```
#### orders()
Returns a list of ndarray orders.
```javascript
var out = orders();
// returns [ 'row-major', 'column-major' ]
```
The output `array` contains the following orders:
- `row-major`: row-major (C-style) order.
- `column-major`: column-major (Fortran-style) order.
## Examples
```javascript
var indexOf = require( '@stdlib/utils/index-of' );
var orders = require( '@stdlib/ndarray/orders' );
var ORDERS = orders();
var bool;
function isOrder( str ) {
if ( indexOf( ORDERS, str ) === -1 ) {
return false;
}
return true;
}
bool = isOrder( 'row-major' );
// returns true
bool = isOrder( 'column-major' );
// returns true
bool = isOrder( 'beep' );
// returns false
```
