+#### 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.
