iterCompositesSeq

Create an iterator which generates a sequence of composite numbers.

Usage

var iterCompositesSeq = require( '@stdlib/math/iter/sequences/composites' );

iterCompositesSeq( [options] )

Returns an iterator which generates a sequence of composite numbers.

var it = iterCompositesSeq();
// returns <Object>

var v = it.next().value;
// returns 4

v = it.next().value;
// returns 6

v = it.next().value;
// returns 8

v = it.next().value;
// returns 9

v = it.next().value;
// returns 10

// ...

The returned iterator protocol-compliant object has the following properties:

  • 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.
  • return: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.

The function supports the following options:

  • iter: number of iterations. Default: 1e308.

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.

var opts = {
    'iter': 2
};
var it = iterCompositesSeq( opts );
// returns <Object>

var v = it.next().value;
// returns 4

v = it.next().value;
// returns 6

var bool = it.next().done;
// returns true

Notes

  • If an environment supports Symbol.iterator, the returned iterator is iterable.

Examples

var iterCompositesSeq = require( '@stdlib/math/iter/sequences/composites' );

// Create an iterator:
var opts = {
    'iter': 100
};
var it = iterCompositesSeq( opts );

// Perform manual iteration...
var v;
while ( true ) {
    v = it.next();
    if ( v.done ) {
        break;
    }
    console.log( v.value );
}
