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!

Typed Array Function

NPM version Build Status Coverage Status

Return a function which tests if every element in a typed array passes a test condition.

Usage

import typedarrayfcn from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-tools-typed-array-function@deno/mod.js';

typedarrayfcn( predicate )

Returns a function which tests if every element in a typed array passes a test condition. Given an input typed array, 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@deno/mod.js';
import Int32Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-int32@deno/mod.js';

var arr1 = new Int32Array( [ 1, 3, 5, 7 ] );
var arr2 = new Int32Array( [ 3, 5, 8 ] );

var f = typedarrayfcn( isOdd );

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

bool = f( arr2 );
// returns false

Notes

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

Examples

import isEven from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-even@deno/mod.js';
import Int32Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-int32@deno/mod.js';
import typedarrayfcn from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-tools-typed-array-function@deno/mod.js';

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

arr1 = new Int32Array( 25 );
for ( i = 0; i < arr1.length; i++ ) {
    arr1[ i ] = i;
}

arr2 = new Int32Array( 25 );
for ( i = 0; i < arr2.length; i++ ) {
    arr2[ i ] = 2 * i;
}

f = typedarrayfcn( isEven );

bool = f( arr1 );
// returns false

bool = f( arr2 );
// returns true
