+
+#### BooleanArray.prototype.copyWithin( target, start\[, end] )
+
+Copies a sequence of elements within the array starting at `start` and ending at `end` (non-inclusive) to the position starting at `target`.
+
+```javascript
+var arr = new BooleanArray( 4 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( false, 2 );
+arr.set( true, 3 );
+
+var v = arr.get( 0 );
+// returns true
+
+v = arr.get( 1 );
+// returns false
+
+// Copy the last two elements to the first two elements:
+arr.copyWithin( 0, 2 );
+
+v = arr.get( 0 );
+// returns false
+
+v = arr.get( 1 );
+// returns true
+```
+
+By default, `end` equals the number of array elements (i.e., one more than the last array index). To limit the sequence length, provide an `end` argument.
+
+```javascript
+var arr = new BooleanArray( 4 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( false, 2 );
+arr.set( true, 3 );
+
+var v = arr.get( 2 );
+// returns false
+
+v = arr.get( 3 );
+// returns true
+
+// Copy the first two elements to the last two elements:
+arr.copyWithin( 2, 0, 2 );
+
+v = arr.get( 2 );
+// returns true
+
+v = arr.get( 3 );
+// returns false
+```
+
+When a `target`, `start`, and/or `end` index is negative, the respective index is determined relative to the last array element. The following example achieves the same behavior as the previous example:
+
+```javascript
+var arr = new BooleanArray( 4 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( false, 2 );
+arr.set( true, 3 );
+
+var v = arr.get( 2 );
+// returns false
+
+v = arr.get( 3 );
+// returns true
+
+// Copy the first two elements to the last two elements using negative indices:
+arr.copyWithin( -2, -4, -2 );
+
+v = arr.get( 2 );
+// returns true
+
+v = arr.get( 3 );
+// returns false
+```

+
+#### BooleanArray.prototype.entries()
+
+Returns an iterator for iterating over array key-value pairs.
+
+```javascript
+var arr = new BooleanArray( 3 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( true, 2 );
+
+var it = arr.entries();
+
+var v = it.next().value;
+// returns [ 0, true ]
+
+v = it.next().value;
+// returns [ 1, false ]
+
+v = it.next().value;
+// returns [ 2, true ]
+
+var bool = it.next().done;
+// returns true
+```
+
+The returned [iterator][mdn-iterator-protocol] protocol-compliant object has the following properties:
+
+-   **next**: function which returns an [iterator][mdn-iterator-protocol] protocol-compliant object containing the next iterated value (if one exists) assigned to a `value` property and a `done` property having a `boolean` value indicating whether the [iterator][mdn-iterator-protocol] is finished.
+-   **return**: function which closes an [iterator][mdn-iterator-protocol] and returns a single (optional) argument in an [iterator][mdn-iterator-protocol] protocol-compliant object.

+<a name="method-for-each"></a>
+
+#### BooleanArray.prototype.forEach( callbackFn\[, thisArg] )
+
+Invokes a function once for each array element.
+
+```javascript
+function log( v, i ) {
+    console.log( '%s: %s', i, v.toString() );
+}
+
+var arr = new BooleanArray( 3 );
+

+
+arr.forEach( log );
+/* =>
+    0: true
+    1: false
+    2: true
+*/
+```
+
+The invoked 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 += 1;
+    console.log( '%s: %s', i, v.toString() );
+}
+
+var arr = new BooleanArray( 3 );
