+# cuanyByRight
+
+> Cumulatively test whether at least one element in a provided array passes a test implemented by a predicate function, while iterating from right-to-left.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var cuanyByRight = require( '@stdlib/array/base/cuany-by-right' );
+```
+
+#### cuanyByRight( x, predicate\[, thisArg] )
+
+Cumulatively tests whether at least one element in a provided array passes a test implemented by a `predicate` function, while iterating from right-to-left.
+
+```javascript
+function isPositive( value ) {
+    return ( value > 0 );
+}
+
+var x = [ 0, 0, 0, 1, 0 ];
+
+var y = cuanyByRight( x, isPositive );
+// returns [ false, true, true, true, true ]
+```
+
+The `predicate` function is provided three arguments:
+
+-   **value**: current array element.
+-   **index**: current array element index.
+-   **arr**: input array.
+
+To set the `predicate` function execution context, provide a `thisArg`.
+
+```javascript
+function isPositive( value ) {
+    this.count += 1;
+    return ( value > 0 );
+}
+
+var x = [ 0, 1, 0, 0, 0 ];
+
+var context = {
+    'count': 0
+};
+
+var out = cuanyByRight( x, isPositive, context );
+// returns [ false, false, false, true, true ]
+
+var cnt = context.count;
+// returns 4
+```
+
+#### cuanyByRight.assign( x, out, stride, offset, predicate\[, thisArg] )
+
+Cumulatively tests whether at least one element in a provided array passes a test implemented by a `predicate` function, while iterating from right-to-left, and assigns results to a provided output array.
+
+```javascript
+function isPositive( value ) {
+    return ( value > 0 );
+}
+
+var x = [ 0, 1, 0, 0, 0 ];
+var y = [ false, null, false, null, false, null, false, null, false, null ];
+
+var out = cuanyByRight.assign( x, y, 2, 0, isPositive );
+// returns [ false, null, false, null, false, null, true, null, true, null ]
+
+var bool = ( out === y );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **x**: input array.
+-   **out**: output array.
+-   **stride**: output array stride.
+-   **offset**: output array offset.
+-   **predicate**: test function.
