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!

iterOddIntegersSeq

Create an iterator which generates an interleaved sequence of odd integers.

Installation

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

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var iterOddIntegersSeq = require( '@stdlib/math-iter-sequences-odd-integers' );

iterOddIntegersSeq( [options] )

Returns an iterator which generates an interleaved sequence of odd integers.

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

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

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

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

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

v = it.next().value;
// returns 5

// ...

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: 9007199254740992.

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 = iterOddIntegersSeq( opts );
// returns <Object>

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

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

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

Notes

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

Examples

var iterOddIntegersSeq = require( '@stdlib/math-iter-sequences-odd-integers' );

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

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