|  | ## Instructions
 | |||
|  | <section id="instructions"> Прочитайте значения свойств <code>testObj</code> с использованием точечной нотации. Установите переменную <code>hatValue</code> равное свойству объекта <code>hat</code> и установить переменную <code>shirtValue</code> равной свойству объекта <code>shirt</code> . </section> | |||
