This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-tools-array-like-function) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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!

Array-Like Function

Return a function which tests if every element in an array-like object passes a test condition.

Installation

npm install @stdlib/assert-tools-array-like-function

Usage

var arraylikefcn = require( '@stdlib/assert-tools-array-like-function' );

arraylikefcn( predicate )

Returns a function which tests if every element in an array-like object passes a test condition. Given an input array-like object, the function returns true if all elements pass the test and false otherwise.

var isOdd = require( '@stdlib/assert-is-odd' );

var arr1 = [ 1, 3, 5, 7 ];
var arr2 = [ 3, 5, 8 ];

var f = arraylikefcn( isOdd );

var bool = f( arr1 );
// returns true

bool = f( arr2 );
// returns false

Notes

The returned function will return false if not provided an array-like object.
The returned function will return false if provided an empty array-like object.
A predicate function should accept a single argument: an element from an array-like object. If the element satisfies a test condition, the predicate function should return true; otherwise, the predicate function should return false.

Examples

var isEven = require( '@stdlib/assert-is-even' );
var arraylikefcn = require( '@stdlib/assert-tools-array-like-function' );

var arr1;
var arr2;
var bool;
var f;
var i;

arr1 = new Array( 25 );
for ( i = 0; i < arr1.length; i++ ) {
    arr1[ i ] = i;
}

arr2 = new Array( 25 );
for ( i = 0; i < arr2.length; i++ ) {
    arr2[ i ] = 2 * i;
}

f = arraylikefcn( isEven );

bool = f( arr1 );
// returns false

bool = f( arr2 );
// returns true

Notice

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.
