+#### TypedArray.prototype.map( callbackFn\[, thisArg] )
+
+Returns a new array with each element being the result of a provided callback function.
+
+```javascript
+function fcn( v ) {
+ return -v;
+}
+
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0 ] );
+// returns
+
+var out = arr.map( fcn );
+// returns
+
+var z = out.get( 0 );
+// returns -1.0
+
+z = out.get( 1 );
+// returns -2.0
+
+z = out.get( 2 );
+// returns -3.0
+```
+
+The callback function is provided three arguments:
+
+- **value**: current array element.
+- **index**: current array element index.
+- **arr**: the array on which this method was called.
+
+To set the function execution context, provide a `thisArg`.
+
+```javascript
+function fcn( v, i ) {
+ this.count += i;
+ return -v;
+}
+
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', 3 );
+
+arr.set( -1.0, 0 );
+arr.set( 1.0, 1 );
+arr.set( -1.0, 2 );
+
+var context = {
+ 'count': 0
+};
+
+var out = arr.map( fcn, context );
+// returns
+
+var count = context.count;
+// returns 3;
