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!
contains
Test if an array contains a provided search value.
Installation
npm install @stdlib/array-base-assert-containsUsage
var contains = require( '@stdlib/array-base-assert-contains' );contains( x, value )
Tests if an array contains a provided search value.
var x = [ 1, 2, 3 ];
var out = contains( x, 2 );
// returns truecontains.factory( x )
Returns a function which tests if an array contains a provided search value.
var x = [ 1, 2, 3 ];
var fcn = contains.factory( x );
// returns <Function>
var out = fcn( 2 );
// returns true
out = fcn( 4 );
// returns falseExamples
var AccessorArray = require( '@stdlib/array-base-accessor' );
var contains = require( '@stdlib/array-base-assert-contains' );
// Create an accessor array:
var arr = new AccessorArray( [ 1, 2, 3, 4 ] );
// Check whether the array contains various values...
var bool = contains( arr, 2 );
// returns true
bool = contains( arr, 4 );
// returns true
bool = contains( arr, 9 );
// returns falseNotice
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
