Выражением тут является анонимная функция `() => {}`, и это накладывает теже ограничения, какие существуют для констант: нельзя переназначить константу и нельзя ее использовать до того, как она объявлена, а так же ограничивается зона видимости по всем правилам создания переменных через `const, let, var`.\r\n\r\nОбъявление через `function () {}` расширяет зону видимости функции и позволяет её использовать до создания функции. Например:\r\n\r\n```javascript\r\nconst hello = myFunc();\r\nconsole.log(hello); // => hello\r\nfunction myFunc() {\r\n return 'hello';\r\n}\r\n```\r\n\r\nТакже у стрелочных функций нет своего контекста, они берут текущий контекст в момент своего создания.

Выражением тут является анонимная функция `() => {}`, и это накладывает теже ограничения, какие существуют для констант: нельзя переназначить константу и нельзя ее использовать до того, как она объявлена, а так же ограничивается зона видимости по всем правилам создания переменных через `const, let, var`.\r\n\r\nОбъявление через `function () {}` расширяет зону видимости функции и позволяет её использовать до создания функции. Например:\r\n\r\n```javascript\r\nconst hello = myFunc();\r\nconsole.log(hello); // => hello\r\nfunction myFunc() {\r\n return 'hello';\r\n}\r\n```\r\n\r\nТакже у стрелочных функций нет своего контекста, они берут текущий контекст в момент своего создания.
