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 Function
Return a function which tests if every element in an array passes a test condition.
Installation
npm install @stdlib/assert-tools-array-function
Usage
var arrayfcn = require( '@stdlib/assert-tools-array-function' );
arrayfcn( predicate )
Returns a function which tests if every element in an array
passes a test condition. Given an input array
, 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 = arrayfcn( isOdd );
var bool = f( arr1 );
bool = f( arr2 );
Notes
- The returned function will return
false
if not provided an array
. - The returned function will return
false
if provided an empty array
. - A
predicate
function should accept a single argument: an array
element. If the array
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 arrayfcn = require( '@stdlib/assert-tools-array-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 = arrayfcn( isEven );
bool = f( arr1 );
bool = f( arr2 );
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.
