About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, wellwritten, studied, documented, tested, measured, and highquality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
iterNonNegativeEvenIntegersSeq
Create an iterator which generates a sequence of nonnegative even integers.
Installation
npm install @stdlib/mathitersequencesnonnegativeevenintegers
Usage
var iterNonNegativeEvenIntegersSeq = require( '@stdlib/mathitersequencesnonnegativeevenintegers' );
iterNonNegativeEvenIntegersSeq( [options] )
Returns an iterator which generates a sequence of nonnegative even integers.
var it = iterNonNegativeEvenIntegersSeq();
// returns <Object>
var v = it.next().value;
// returns 0
v = it.next().value;
// returns 2
v = it.next().value;
// returns 4
// ...
The returned iterator protocolcompliant object has the following properties:

next: function which returns an iterator protocolcompliant object containing the next iterated value (if one exists) assigned to a
value
property and adone
property having aboolean
value indicating whether the iterator is finished.  return: function which closes an iterator and returns a single (optional) argument in an iterator protocolcompliant object.
The function supports the following options
:

iter: number of iterations. Default:
4503599627370497
.
By default, the function returns a finite iterator to avoid exceeding the maximum safe doubleprecision floatingpoint integer. To adjust the number of iterations, set the iter
option.
var opts = {
'iter': 2
};
var it = iterNonNegativeEvenIntegersSeq( opts );
// returns <Object>
var v = it.next().value;
// returns 0
v = it.next().value;
// returns 2
var bool = it.next().done;
// returns true
Notes
 If an environment supports
Symbol.iterator
, the returned iterator is iterable.
Examples
var iterNonNegativeEvenIntegersSeq = require( '@stdlib/mathitersequencesnonnegativeevenintegers' );
// Create an iterator:
var opts = {
'iter': 100
};
var it = iterNonNegativeEvenIntegersSeq( opts );
// Perform manual iteration...
var v;
while ( true ) {
v = it.next();
if ( v.done ) {
break;
}
console.log( v.value );
}
