@stdlib/array-base-every v0.2.1

every

Test whether all elements in an array are truthy.

Installation

npm install @stdlib/array-base-every

Usage

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

every( x )

Tests whether all elements in an array are truthy.

var x = [ 1, 2, 3, 4 ];

var bool = every( x );
// returns true

Notes

• If provided an empty array, the function returns true.
• The function does not skip undefined elements and is thus not optimized for sparse arrays.

Examples

var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var every = require( '@stdlib/array-base-every' );

var x = discreteUniform( 10, 0, 10, {
    'dtype': 'int32'
});
// returns <Int32Array>

var out = every( x );
// returns <boolean>
