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!
Return a function which tests if every element in an array-like object passes a test condition.
import arraylikefcn from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-tools-array-like-function@esm/index.mjs';
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.
import isOdd from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-odd@esm/index.mjs'; 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
- The returned function will return
falseif not provided an array-like object. - The returned function will return
falseif provided an empty array-like object. - A
predicatefunction should accept a single argument: an element from an array-like object. If the element satisfies a test condition, thepredicatefunction should returntrue; otherwise, thepredicatefunction should returnfalse.

This package is part of stdlib, a standard library 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.
