+#### BooleanArray.prototype.indexOf( searchElement\[, fromIndex] )
+
+Returns the first index at which a given element can be found.
+
+```javascript
+var arr = new BooleanArray( 5 );
+
+arr.set( true, 0 );
+arr.set( false, 1 );
+arr.set( true, 2 );
+arr.set( true, 3 );

+// returns 0
+
+idx = arr.indexOf( false, 1 );
+// returns 1
+
+idx = arr.indexOf( true, -3 );
+// returns 2
+```
+
+If `searchElement` is not present in the array, the method returns `-1`.
+
+```javascript
+var arr = new BooleanArray( 3 );
+
+arr.set( true, 0 );
+arr.set( true, 1 );

+arr.set( true, 0 );
+arr.set( true, 1 );
+arr.set( true, 2 );
