// returns true

If provided a string, the function returns false.

var bool = isArrayLikeObject( 'beep' );
// returns false

Examples

var Float64Array = require( '@stdlib/array-float64' );
var isArrayLikeObject = require( '@stdlib/assert-is-array-like-object' );

var bool = isArrayLikeObject( { 'length': 10 } );
// returns true

bool = isArrayLikeObject( [] );
// returns true

bool = isArrayLikeObject( new Float64Array( 10 ) );
// returns true

bool = (function test() {
    return isArrayLikeObject( arguments );
})();
// returns true

bool = isArrayLikeObject( 'beep' );
// returns false

bool = isArrayLikeObject( null );
// returns false

bool = isArrayLikeObject( void 0 );
// returns false

bool = isArrayLikeObject( 5 );
// returns false

bool = isArrayLikeObject( true );
// returns false
