Алгоритм сравнения
Сравнение x==y , где x и y значения представляют true or false. Эти значения выполнены следующим образом:
1. Если Тип X такой же как тип Y, тогда:
a. Если Тип X undefined возвращает true.
b. Если Тип X Null возвращает true.
c. Если Тип X number тогда
i. если X NaN возвращает false.
ii. если Y NaN возвращает false.
iii.Если X такой же как Number и значение Y возвращает true.
iv. Если X +0 и Y -0 возвращает true.
