+# iterCuAnyBy
+
+> Create an iterator which cumulatively tests whether at least one iterated value passes a test implemented by a predicate function.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var iterCuAnyBy = require( '@stdlib/iter/cuany-by' );
+```
+
+#### iterCuAnyBy( iterator, predicate\[, thisArg] )
+
+Returns an [iterator][mdn-iterator-protocol] which cumulatively tests whether at least one iterated value passes a test implemented by a `predicate` function.
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function predicate( v ) {
+ return ( v > 0 );
+}
+
+var arr = array2iterator( [ 0, 0, 0, 1, 0 ] );
+
+var it = iterCuAnyBy( arr, predicate );
+
+var v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns true
+
+v = it.next().value;
+// returns 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 `predicate` function is provided two arguments:
+
+- **value**: iterated value
+- **index**: iteration index (zero-based)
+
+To set the `predicate` function execution context, provide a `thisArg`.
+
+
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function predicate( v ) {
+ this.count += 1;
+ return ( v < 0 );
+}
+
+var ctx = {
+ 'count': 0
+};
+
+var it = iterCuAnyBy( array2iterator( [ 1, 2, -1, 4 ] ), predicate, ctx );
+// returns
+
+
+
+
+
+
+
+## Notes
+
+- A `predicate` function is invoked for each iterated value until the first truthy `predicate` function return value. Upon encountering the first truthy return value, the returned iterator ceases to invoke the `predicate` function and returns `true` for each subsequent iterated value of the provided input `iterator`.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/iter/randu' );
+var iterCuAnyBy = require( '@stdlib/iter/cuany-by' );
+
+function threshold( r ) {
+ return ( r > 0.95 );
+}
+
+// Create an iterator which generates uniformly distributed pseudorandom numbers:
+var opts = {
+ 'iter': 100
+};
+var riter = randu( opts );
+
+// Create an iterator which cumulatively tests whether at least one iterated value passes a test implemented by a predicate function:
+var it = iterCuAnyBy( riter, threshold );
+
+// Perform manual iteration...
+var r;
+while ( true ) {
+ r = it.next();
+ if ( r.done ) {
+ break;
+ }
+ console.log( r.value );
+}
+```

+{{alias}}( iterator, predicate[, thisArg] )
+ Returns an iterator which cumulatively tests whether at least one iterated
+ value passes a test implemented by a predicate function.
+
+ If an environment supports Symbol.iterator and a provided iterator is
+ iterable, the returned iterator is iterable.
+
+ The predicate function is provided two arguments:
+
+ - value: iterated value
+ - index: iteration index
+
+ A predicate function is invoked for each iterated value until the first
+ truthy predicate function return value. Upon encountering the first truthy
+ return value, the returned iterator ceases to invoke the predicate function
+ and returns `true` for each subsequent iterated value of the provided input
+ iterator.
+
+ If provided an iterator which does not return any iterated values, the
+ function returns an iterator which is also empty.
+
+ Parameters
+ ----------
+ iterator: Object
+ Input iterator.
+
+ predicate: Function
+ The test function.
+
+ thisArg: any (optional)
+ Execution context.
+
+ 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}}( [ 0, 0, 0, 1, 0 ] );
+ > function fcn( v ) { return ( v > 0 ); };

+# iterCuEveryBy
+
+> Create an iterator which cumulatively tests whether every iterated value passes a test implemented by a predicate function.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var iterCuEveryBy = require( '@stdlib/iter/cuevery-by' );
+```
+
+#### iterCuEveryBy( iterator, predicate\[, thisArg] )
+
+Returns an [iterator][mdn-iterator-protocol] which cumulatively tests whether every iterated value passes a test implemented by a `predicate` function.
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function predicate( v ) {
+ return ( v > 0 );
+}
+
+var arr = array2iterator( [ 1, 1, 1, 0, 1 ] );
+
+var it = iterCuEveryBy( arr, predicate );
+
+var v = it.next().value;
+// returns true
+
+v = it.next().value;
+// returns true
+
+v = it.next().value;
+// returns true
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+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 `predicate` function is provided two arguments:
+
+- **value**: iterated value
+- **index**: iteration index (zero-based)
+
+To set the `predicate` function execution context, provide a `thisArg`.
+
+
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function predicate( v ) {
+ this.count += 1;
+ return ( v > 0 );
+}
+
+var ctx = {
+ 'count': 0
+};
+
+var it = iterCuEveryBy( array2iterator( [ 1, 2, 3, 4 ] ), predicate, ctx );
+// returns
+
+
+
+
+
+
+
+## Notes
+
+- A `predicate` function is invoked for each iterated value until the first falsy `predicate` function return value. Upon encountering the first falsy return value, the returned iterator ceases to invoke the `predicate` function and returns `false` for each subsequent iterated value of the provided input `iterator`.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/iter/randu' );
+var iterCuEveryBy = require( '@stdlib/iter/cuevery-by' );
+
+function threshold( r ) {
+ return ( r > 0.05 );
+}
+
+// Create an iterator which generates uniformly distributed pseudorandom numbers:
+var opts = {
+ 'iter': 100
+};
+var riter = randu( opts );
+
+// Create an iterator which cumulatively tests whether every iterated value passes a test:
+var it = iterCuEveryBy( riter, threshold );
+
+// Perform manual iteration...
+var r;
+while ( true ) {
+ r = it.next();
+ if ( r.done ) {
+ break;
+ }
+ console.log( r.value );
+}
+```

+{{alias}}( iterator, predicate[, thisArg] )
+ Returns an iterator which cumulatively tests whether every iterated value
+ passes a test implemented by a predicate function.
+
+ If an environment supports Symbol.iterator and a provided iterator is
+ iterable, the returned iterator is iterable.
+
+ The predicate function is provided two arguments:
+
+ - value: iterated value
+ - index: iteration index
+
+ A predicate function is invoked for each iterated value until the first
+ falsy predicate function return value. Upon encountering the first falsy
+ return value, the returned iterator ceases to invoke the predicate function
+ and returns `false` for each subsequent iterated value of the provided input
+ iterator.
+
+ If provided an iterator which does not return any iterated values, the
+ function returns an iterator which is also empty.
+
+ Parameters
+ ----------
+ iterator: Object
+ Input iterator.
+
+ predicate: Function
+ The test function.
+
+ thisArg: any (optional)
+ Execution context.
+
+ 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 ] );
+ > function fcn( v ) { return ( v > 0 ); };
+ > var it = {{alias}}( arr, fcn );

+ > v = it.next().value

+# 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

+# iterCuSomeBy
+
+> Create an iterator which cumulatively tests whether at least `n` iterated values pass a test implemented by a predicate function.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var iterCuSomeBy = require( '@stdlib/iter/cusome-by' );
+```
+
+#### iterCuSomeBy( iterator, n, predicate\[, thisArg] )
+
+Returns an [iterator][mdn-iterator-protocol] which cumulatively tests whether at least `n` iterated values pass a test implemented by a `predicate` function.
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function isPositive( v ) {
+ return ( v > 0 );
+}
+
+var arr = array2iterator( [ 0, 0, 0, 1, 1 ] );
+
+var it = iterCuSomeBy( arr, 2, isPositive );
+
+var v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns false
+
+v = it.next().value;
+// returns 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 `predicate` function is provided two arguments:
+
+- **value**: iterated value
+- **index**: iteration index (zero-based)
+
+To set the `predicate` function execution context, provide a `thisArg`.
+
+
+
+```javascript
+var array2iterator = require( '@stdlib/array/to-iterator' );
+
+function predicate( v ) {
+ this.count += 1;
+ return ( v > 0 );
+}
+
+var arr = array2iterator( [ 0, 0, 1, 1, 1 ] );
+
+var ctx = {
+ 'count': 0
+};
+
+var it = iterCuSomeBy( arr, 3, predicate, ctx );
+// returns
+
+
+
+
+
+
+
+## Notes
+
+- A `predicate` function is invoked for each iterated value until the `nth` truthy `predicate` function return value. The returned iterator continues iterating until it reaches the end of the input iterator, even after the condition is met.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var randu = require( '@stdlib/random/iter/randu' );
+var iterCuSomeBy = require( '@stdlib/iter/cusome-by' );
+
+function threshold( r ) {
+ return ( r > 0.95 );
+}
+
+// Create an iterator which generates uniformly distributed pseudorandom numbers:
+var opts = {
+ 'iter': 100
+};
+var riter = randu( opts );
+
+// Create an iterator which tracks whether at least two values have exceeded the threshold:
+var it = iterCuSomeBy( riter, 2, threshold );
+
+// Perform manual iteration...
+var r;
+while ( true ) {
+ r = it.next();
+ if ( r.done ) {
+ break;
+ }
+ console.log( r.value );
+}
+```

+
+{{alias}}( iterator, n, predicate[, thisArg] )
+ Returns an iterator which cumulatively tests whether at least `n` iterated
+ values pass a test implemented by a predicate function.
+
+ If an environment supports Symbol.iterator and a provided iterator is
+ iterable, the returned iterator is iterable.
+
+ The predicate function is provided two arguments:
+
+ - value: iterated value
+ - index: iteration index
+
+ A predicate function is invoked for each iterated value until the n
+ truthy predicate function return value. Upon encountering the nth truthy
+ return value, the returned iterator ceases to invoke the predicate function
+ and returns `true` for each subsequent iterated value of the provided input
+ iterator.
+
+ If provided an iterator which does not return any iterated values, the
+ function returns an iterator which is also empty.
+
+ Parameters
+ ----------
+ iterator: Object
+ Input iterator.
+
+ n: integer
+ Number of successful values to check for.
+
+ predicate: Function
+ The test function.
+
+ thisArg: any (optional)
+ Execution context.
+
+ 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}}( [ 0, 0, 0, 1, 1 ] );
+ > function fcn( v ) { return ( v > 0 ); };
+ > var it = {{alias}}( arr, 2, fcn );
+ > var v = it.next().value

+ > v = it.next().value
