+# iterCuEvery
+
+> Create an [iterator][mdn-iterator-protocol] which cumulatively tests whether every iterated value is truthy.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var iterCuEvery = require( '@stdlib/iter/cuevery' );
+```
+
+#### iterCuEvery( iterator )
+
+Returns an [iterator][mdn-iterator-protocol] which cumulatively tests whether every iterated value is truthy.
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+var arr = array2iterator( [ 1, 1, 1, 0, 1 ] );
+
+var it = iterCuEvery( arr );
+// returns
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/iter/randu' );
+var iterMap = require( '@stdlib/iter/map' );
+var iterCuEvery = require( '@stdlib/iter/cuevery' );
+
+function threshold( r ) {
+ return ( r > 0.1 );
+}
+
+// Create an iterator which generates uniformly distributed pseudorandom numbers:
+var opts = {
+ 'iter': 100
+};
+var riter = randu( opts );
+
+// Create an iterator which applies a threshold to generated numbers:
+var miter = iterMap( riter, threshold );
+
+// Create an iterator which cumulatively tests whether every iterated value is truthy:
+var it = iterCuEvery( miter );
+
+// Perform manual iteration...
+var r;
+while ( true ) {
+ r = it.next();
+ if ( r.done ) {
+ break;
+ }
+ console.log( r.value );
+}

+
+{{alias}}( iterator )
+ Returns an iterator which cumulatively tests whether every iterated value is
+ truthy.
+
+ If an environment supports Symbol.iterator and a provided iterator is
+ iterable, the returned iterator is iterable.
+
+ Parameters
+ ----------
+ iterator: Object
+ Input iterator.
+
+ Returns
+ -------
+ iterator: Object
+ Iterator.
+
+ iterator.next(): Function
+ Returns an iterator protocol-compliant object containing the next
+ iterated value (if one exists) and a boolean flag indicating whether the
+ iterator is finished.
+
+ iterator.return( [value] ): Function
+ Finishes an iterator and returns a provided value.
+
+ Examples
+ --------
+ > var arr = {{alias:@stdlib/array/to-iterator}}( [ 1, 1, 1, 0, 1 ] );
+ > var it = {{alias}}( arr );
+ > var v = it.next().value
+ true
+ > v = it.next().value
+ true
+ > v = it.next().value
