Этот синтаксис существует только на уровне проверки типов. В результирующем коде он вырезается или заменяется. В этом уроке мы изучим реализацию таких классов.\n\n## Определение полей внутри класса\n\nНачнем с примера. Посмотрите на этот класс:\n\n```typescript\nclass Point {\n x: number\n\n y: number\n\n constructor(x: number, y: number) {\n this.x = x\n this.y = y\n }\n}\n\nconst p = new Point(10, 20)\nconsole.log(p) // { x: 10, y: 20 }\n```\n\nЗдесь мы видим новый синтаксис, который описывает поля класса: `x` и `y`. Их описание обязательно, потому что классы — это функции-конструкторы, а функции в TypeScript являются объектами.\n\nОпределение полей внутри класса появилось в JavaScript, начиная со стандарта es2022. Перед тем как двигаться дальше, разберемся с понятием «поле класса».\n\n## Поле класса\n\nОбычно в JavaScript все называют свойствами. А слово «поле» используют как синоним те, кто пришел из других языков. Но это не одно и тоже. Внутри класса мы определяем **поля** — это данные самого класса. А **свойство** — это то, с помощью чего мы взаимодействуем с объектом.\n\nЧасто свойства отображаются на поля напрямую, но так происходит не всегда. Например, свойство может быть геттером, который берет информацию из поля. Или свойство может быть сеттером, который устанавливает новое значение поля:\n\n```typescript\nclass Point {\n x: number\n\n y: number\n\n // Возвращаемый тип не указывается, потому что это конструктор\n constructor(x: number, y: number) {\n this.x = x\n this.y = y\n }\n\n get inspect(): string {\n return `(${this.x}, ${this.y})`\n }\n}\n\nconst p = new Point(2, 5)\n// Свойство есть, а поля такого нет\nconsole.log(p.inspect) // (2, 5)\n```\n\nПоля могут быть инициализированы сразу при определении класса. Это удобно, когда конструктор не нужен или данные не зависят от его вызова — задаются статически внутри:\n\n```typescript\nclass Point {\n x = 0\n\n y = 0\n}\n\nconst p = new Point()\nconsole.log(p) // { x: 0, y: 0 }\n```\n\nКак и в случае обычных переменных, тип полей выводится автоматически во время их инициализации, поэтому указывать явный тип не обязательно.\n"},"id":384,"slug":"typescript-advanced","challenges_count":4,"name":"Продвинутый Typescript","allow_indexing":true,"state":"approved","course_state":"finished","pricing_type":"paid","description":"На этом курсе вы продолжите изучать Typescript.
