+# cueveryByRight
+
+> Cumulatively test whether every array element in a provided array pass a test implemented by a predicate function, while iterating from right-to-left.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var cueveryByRight = require( '@stdlib/array/base/cuevery-by-right' );
+```
+
+#### cueveryByRight( x, predicate\[, thisArg ] )
+
+Cumulatively test whether every array element in a provided array pass a test implemented by a `predicate` function, while iterating from right-to-left.
+
+```javascript
+function fcn( value ) {
+    return value > 0;
+}
+
+var x = [ 0, 0, 1, 1, 1 ];
+
+var y = cueveryByRight( x, fcn );
+// returns [ true, true, true, false, false ];
+```
+
+#### cueveryByRight.assign( x, out, stride, offset, predicate\[, thisArg ] )
+
+Cumulatively test whether every array element in a provided array pass a test implemented by a `predicate` function, while iterating from right-to-left and assign the results to the elements in the output array.
+
+```javascript
+function fcn( v ) {
+    return v > 0;
+}
+
+var x = [ 0, 0, 1, 1, 1 ];
+var y = [ false, null, false, null, false, null, false, null, false, null ];
+
+var out = cueveryByRight.assign( x, y, 2, 0, fcn );
+// returns [ true, null, true, null, true, null, false, null, false, null ]
+
+var bool = ( out === y );
+// returns true
+```
+
+The invoked `predicate` function is provided three arguments:
+
+-   `value`: collection element,
+-   `index`: collection index,
+-   `collection`: input collection,
+
+To set the function execution context, provide a `thisArg`.
+
+```javascript
+function fcn( v ) {
+    this.count += 1;
+    return ( v > 0 );
+}
+
+var x = [ 0, 0, 1, 1, 1 ];
+
+var context = {
+    'count': 0
+};
+
+var bool = cueveryByRight( x, fcn, context );
+// returns [ true, true, true, false, false ]
+
+var count = context.count;
+// returns 4
+```
