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, well-written, studied, documented, tested, measured, and high-quality 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!


NPM version Build Status Coverage Status

Create an iterator which generates a positive integer sequence.

The sequence of positive integers 1, 2, 3, 4, ... (OEIS A000027) is also commonly referred to the sequence of natural numbers, whole numbers, and counting numbers; however, those terms are ambiguous due to the inclusion or exclusion of 0.


npm install @stdlib/math-iter-sequences-positive-integers


var iterPositiveIntegersSeq = require( '@stdlib/math-iter-sequences-positive-integers' );

iterPositiveIntegersSeq( [options] )

Returns an iterator which generates a positive integer sequence.

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

var v = it.next().value;
// returns 1

v = it.next().value;
// returns 2

v = it.next().value;
// returns 3

// ...

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: 9007199254740991.

By default, the function returns a finite iterator to avoid exceeding the maximum safe double-precision floating-point integer. To adjust the number of iterations, set the iter option.

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

var v = it.next().value;
// returns 1

v = it.next().value;
// returns 2

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


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


var iterPositiveIntegersSeq = require( '@stdlib/math-iter-sequences-positive-integers' );

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

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