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-functionUsage
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 );
// returns true
bool = f( arr2 );
// returns falseNotes
- The returned function will return
falseif not provided anarray. - The returned function will return
falseif provided an emptyarray. - A
predicatefunction should accept a single argument: anarrayelement. If thearrayelement satisfies a test condition, thepredicatefunction should returntrue; otherwise, thepredicatefunction should returnfalse.
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 );
// returns false
bool = f( arr2 );
// returns trueNotice
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.
