Test if a value is an array-like object of booleans.
To use in Observable,
isBooleanArray = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-boolean-array@umd/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var isBooleanArray = require( 'path/to/vendor/umd/assert-is-boolean-array/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-boolean-array@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.isBooleanArray;
})();
</script>Tests if a value is an array-like object of booleans.
var bool = isBooleanArray( [ true, false, false, true ] );
// returns trueTests if a value is an array-like object containing only boolean primitives.
var bool = isBooleanArray.primitives( [ true, false ] );
// returns true
bool = isBooleanArray.primitives( [ false, new Boolean( true ) ] );

var bool = isBooleanArray.objects( [ new Boolean( false ), new Boolean( true ) ] );
