#### TypedArrayFE.prototype.some( predicate\[, thisArg] )

Tests whether any element in an array pass a test implemented by a predicate function.

```javascript
function isPositive( v ) {
return v > 0;
}

var Float64ArrayFE = fixedEndianFactory( 'float64' );

var arr = new Float64ArrayFE( 'little-endian', [ -1.0, 2.0, -3.0, -4.0 ] );

var bool = arr.some( isPositive );
// returns true
```

The invoked function is provided three arguments:

- **value**: current array element.
