# assignScalar
> Assign a scalar value to every element of an output [ndarray][@stdlib/ndarray/base/ctor].
## Usage
```javascript
var assignScalar = require( '@stdlib/ndarray/base/assign-scalar' );
```
#### assignScalar( arrays )
Assigns a scalar value to every element of an output [ndarray][@stdlib/ndarray/base/ctor].
```javascript
var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
var Float64Array = require( '@stdlib/array/float64' );
// Create a zero-dimensional ndarray containing the scalar value:
var x = scalar2ndarray( 5.0, {
'dtype': 'float64'
});
// Create a data buffer:
var ybuf = new Float64Array( 6 );
// Define the shape of the output array:
var shape = [ 3, 1, 2 ];
// Define the array strides:
var sy = [ 2, 2, 1 ];
// Define the index offset:
var oy = 0;
// Create the output ndarray-like object:
var y = {
'dtype': 'float64',
'data': ybuf,
'shape': shape,
'strides': sy,
'offset': oy,
'order': 'row-major'
};
// Assign the scalar value:
assignScalar( [ x, y ] );
console.log( y.data );
// => [ 5.0, 5.0, 5.0, 5.0, 5.0, 5.0 ]
```
The function accepts the following arguments:
- **arrays**: array-like object containing a zero-dimensional input [ndarray][@stdlib/ndarray/base/ctor] and an output [ndarray][@stdlib/ndarray/base/ctor].
Each provided [ndarray][@stdlib/ndarray/base/ctor] should be an object with the following properties:
- **dtype**: data type.
- **data**: data buffer.
- **shape**: dimensions.
- **strides**: stride lengths.
- **offset**: index offset.
- **order**: specifies whether an ndarray is row-major (C-style) or column-major (Fortran-style).
## Examples
```javascript
var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
var filledarray = require( '@stdlib/array/filled' );
var ndarray2array = require( '@stdlib/ndarray/base/to-array' );
var assignScalar = require( '@stdlib/ndarray/base/assign-scalar' );
var x = scalar2ndarray( 10.0, {
'dtype': 'generic'
});
console.log( ndarray2array( x.data, x.shape, x.strides, x.offset, x.order ) );
var y = {
'dtype': 'generic',
'data': filledarray( 0, 10, 'generic' ),
'shape': [ 5, 2 ],
'strides': [ 2, 1 ],
'offset': 0,
'order': 'row-major'
};
console.log( ndarray2array( y.data, y.shape, y.strides, y.offset, y.order ) );
assignScalar( [ x, y ] );
console.log( ndarray2array( y.data, y.shape, y.strides, y.offset, y.order ) );
