# isSameValue
> Test if two arguments are the same value.
## Usage
```javascript
var isSameValue = require( '@stdlib/assert/is-same-value' );
```
#### isSameValue( a, b )
Tests if two arguments `a` and `b` are the same value.
```javascript
var bool = isSameValue( false, false );
// returns true
bool = isSameValue( '', '' );
// returns true
bool = isSameValue( {}, {} );
// returns false
```
In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the same value.
```javascript
var bool = ( 0.0 === -0.0 );
// returns true
bool = isSameValue( 0.0, -0.0 );
// returns false
bool = isSameValue( -0.0, -0.0 );
// returns true
bool = ( NaN === NaN );
// returns false
bool = isSameValue( NaN, NaN );
// returns true
```
## Notes
- The function implements the [SameValue Algorithm][ecma-262-same-value-algorithm] as specified in ECMAScript 5.
## Examples
```javascript
var isSameValue = require( '@stdlib/assert/is-same-value' );
var bool = isSameValue( true, true );
// returns true
bool = isSameValue( true, false );
// returns false
bool = isSameValue( 'beep', 'beep' );
// returns true
bool = isSameValue( 3.14, 3.14 );
// returns true
bool = isSameValue( null, null );
// returns true
bool = isSameValue( 0.0, 0.0 );
// returns true
bool = isSameValue( -0.0, 0.0 );
// returns false
bool = isSameValue( NaN, NaN );
// returns true
bool = isSameValue( {}, {} );
// returns false
bool = isSameValue( [], [] );
// returns false
bool = isSameValue( isSameValue, isSameValue );
// returns true
```
