## Обобщение

<<<<<<< HEAD
- Операторите за сравнение връщат булева стойност.
- Символните низове(текст) се сравняват символ по символ в "лексикографски" ред.
- Когато се сравняват стойности от различни типове, те се преобразуват в числа (с изключение на строга проверка за равенство).
- Стойностите `null` и `undefined` са равни `==` само една на друга, и на никоя друга стойност.
- Бъдете внимателни, когато използвате сравнения като `>` или `<` с променливи, които понякога могат да бъдат `null/undefined`. Проверката за `null/undefined` отделно е добра идея.
=======
- Comparison operators return a boolean value.
- Strings are compared letter-by-letter in the "dictionary" order.
- When values of different types are compared, they get converted to numbers (with the exclusion of a strict equality check).
- The values `null` and `undefined` are equal `==` to themselves and each other, but do not equal any other value.
- Be careful when using comparisons like `>` or `<` with variables that can occasionally be `null/undefined`. Checking for `null/undefined` separately is a good idea.

Some programming languages allow the use of negative indexes for the same purpose, like `fruits[-1]`.

Although, in JavaScript it won't work. The result will be `undefined`, because the index in square brackets is treated literally.
However, in JavaScript it won't work. The result will be `undefined`, because the index in square brackets is treated literally.

We can explicitly calculate the last element index and then access it: `fruits[fruits.length - 1]`.
