Про это

Как вы называете переменную, когда нужно сохранить this в замыкании?

Вопрос не праздный, ведь это дело даже не личного вкуса, а, скорее, договоренности. В коде проекта, над которым я сейчас активно работаю, можно было с равной степенью вероятности встретить that и self. Через два года разработки, впрочем, баланс заметно сместился в сторону that.
