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!
Split array element values into two groups.
import bifurcateValues from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-bifurcate-values@deno/mod.js';Splits array element values into two groups.
var x = [ 'beep', 'boop', 'foo', 'bar' ];
var filter = [ true, true, false, true ];
var out = bifurcateValues( x, filter );
// returns [ [ 'beep', 'boop', 'bar' ], [ 'foo' ] ]- If an element in
filteris truthy, the corresponding element in the input arrayxbelongs to the first group; otherwise, the input array element belongs to the second group.

// Define an initial array of values:
var values = [ 'beep', 'boop', 'foo', 'bar', 'woot', 'woot' ];
// Sample from the initial array to generate a random collection:
var indices = discreteUniform( 100, 0, values.length-1, {
'dtype': 'generic'
});
var x = take( values, indices );
// returns [...]
// Randomly assign collection values to groups:
var groups = discreteUniform( x.length, 0, 1, {
'dtype': 'generic'
});
// Group the values:
var out = bifurcateValues( x, groups );
// returns [...]
console.log( out );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.
