@stdlib/array-base-cunone NPM

cunone

Cumulatively test whether every element in a provided array is falsy.

Installation

npm install @stdlib/array-base-cunone

Usage

var cunone = require( '@stdlib/array-base-cunone' );

cunone( x )

Cumulatively tests whether every element in a provided array is falsy.

var x = [ false, false, false, true, false ];

var y = cunone( x );
// returns [ true, true, true, false, false ];

cunone.assign( x, out, stride, offset )

Cumulatively tests whether every element in a provided array is falsy and assigns results to a provided output array.

var x = [ false, false, false, true, false ];
var y = [ false, null, false, null, false, null, false, null, false, null ];

var out = cunone.assign( x, y, 2, 0 );
// returns [ true, null, true, null, true, null, false, null, false, null ]

var bool = ( out === y );
// returns true

The function supports the following parameters:

x: input array.
out: output array.
stride: output array stride.
offset: output array offset.

Examples

var bernoulli = require( '@stdlib/random-array-bernoulli' );
var cunone = require( '@stdlib/array-base-cunone' );

// Create an array of random values:
var x = bernoulli( 10, 0.1 );
console.log( x );

// Cumulatively determine whether values are falsy:
var out = cunone( x );
console.log( out );
