     37 ## Usage
     38 
     39 ```javascript
     40 var iterCompositesSeq = require( '@stdlib/math/iter/sequences/composites' );
     41 ```
     42 
     43 #### iterCompositesSeq( \[options] )
     44 
     45 Returns an iterator which generates a sequence of composite numbers.
     46 
     47 ```javascript
     48 var it = iterCompositesSeq();
     49 // returns <Object>
     50 
     51 var v = it.next().value;
     52 // returns 4
     53 
     54 v = it.next().value;
     55 // returns 6
     56 
     57 v = it.next().value;
     58 // returns 8
     59 
     60 v = it.next().value;
     61 // returns 9
     62 
     63 v = it.next().value;
     64 // returns 10
     65 
     66 // ...
     67 ```
     68 
     69 The returned iterator protocol-compliant object has the following properties:
     70 
     71 -   **next**: function which returns an iterator 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 is finished.
     72 -   **return**: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.
     73 
     74 The function supports the following `options`:
     75 
     76 -   **iter**: number of iterations. Default: `1e308`.
     77 
     78 By default, the function returns an infinite iterator (i.e., an iterator which never ends). To adjust the number of iterations, set the `iter` option.
     79 
     80 ```javascript
     81 var opts = {
     82     'iter': 2
     83 };
     84 var it = iterCompositesSeq( opts );
     85 // returns <Object>
     86 
     87 var v = it.next().value;
     88 // returns 4
     89 
     90 v = it.next().value;
     91 // returns 6
     92 
     93 var bool = it.next().done;
     94 // returns true
     95 ```

    105 ## Notes
    106 
    107 -   If an environment supports `Symbol.iterator`, the returned iterator is iterable.
