## same-value-zero-x
ES6-compliant shim for SameValueZero.
**See**: [7.2.10 SameValueZero(x, y)](http://www.ecma-international.org/ecma-262/6.0/#sec-samevaluezero)
<a name="exp_module_same-value-zero-x--module.exports"></a>
### `module.exports(x, y)` ⇒ <code>boolean</code> ⏏
This method determines whether two values are the same value.
SameValueZero differs from SameValue (`Object.is`) only in its treatment
of +0 and -0.
**Kind**: Exported function
**Returns**: <code>boolean</code> - A Boolean indicating whether or not the two arguments
are the same value.
| Param | Type | Description |
| ----- | --------------- | ---------------------------- |
| x | <code>\*</code> | The first value to compare. |
| y | <code>\*</code> | The second value to compare. |
**Example**
```js
import sameValueZero from 'same-value-zero-x';
console.log(sameValueZero(0, 0)); // true
console.log(sameValueZero(-0, -0)); // true
console.log(sameValueZero(0, -0)); // true
console.log(sameValueZero(NaN, NaN)); //true
console.log(sameValueZero(Infinity, Infinity)); // true
console.log(sameValueZero(-Infinity, -Infinity)); // true
```
