Instanceof

Checks if variable is instance of some constructor.
Also can detect any type with Instanceof.getType()

Usage:

``js
const Instanceof = require( 'instanceof' );

// Instanceof( {mixed}, {Array|mixed} ) => Boolean

Instanceof( 123, Number ); // true
Instanceof( 123, [ Number, Array, String, 'Boolean' ] ); // true
Instanceof( [], [ Number, Array ] ); // true
Instanceof( [], 'Array' ); // true
Instanceof( NaN, NaN ); // true
Instanceof( Object, Function ); // true

Instanceof( '123', Number ); // false
Instanceof( Object, Object ); // false
Instanceof( Object, [ Object, 'NaN', 'Null', null ] ); // false
Instanceof( 123, [ Object, 'NaN', 'Null', null, 'null' ] ); // false

// --- GetType ---

Instanceof.getType( NaN ); // 'NaN'
Instanceof.getType( { a: 123 } ); // 'object'
Instanceof.getType( [ 1, 2, 3 ] ); // 'array'
Instanceof.getType( null ); // 'null'
