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!

any

NPM version Build Status Coverage Status

Test whether at least one element in a collection is truthy.

Installation

npm install @stdlib/utils-any

Usage

var any = require( '@stdlib/utils-any' );

any( collection )

Tests whether at least one element in a collection is truthy.

var arr = [ 0, 0, 0, 0, 1 ];

var bool = any( arr );
// returns true

If provided an empty collection, the function returns false.

var bool = any( [] );
// returns false

Notes

  • A collection may be either an Array, Typed Array, or an array-like Object (excluding strings and functions).
  • The function does not skip undefined elements and is thus not optimized for sparse collections.

Examples

var randu = require( '@stdlib/random-base-randu' );
var any = require( '@stdlib/utils-any' );

var bool;
var arr;
var i;

arr = [];
for ( i = 0; i < 100; i++ ) {
    arr.push( ( randu() > 0.95 ) );
}

bool = any( arr );
// returns <boolean>
