cuany

Cumulatively test whether at least one element in a provided array is truthy.

Usage

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

cuany( x )

Cumulatively tests whether at least one element in a provided array is truthy.

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

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

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

Cumulatively tests whether at least one element in a provided array is truthy and assigns results to a provided output array.

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

var out = cuany.assign( x, y, 2, 0 );
// returns [ false, null, false, null, true, null, true, null, true, 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 cuany = require( '@stdlib/array/base/cuany' );

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

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