Most props on a JSX element are passed on to the component, however, there are two special props (`ref` and `key`) which are used by React, and are thus not forwarded to the component. | ||
Как правило, свойства, объявленные в JSX, напрямую передаются компоненту. Однако, есть два специальных пропса (`ref` и `key`), которые используются React напрямую, и поэтому компонент их не получает. | ||

For instance, attempting to access `this.props.key` from a component (i.e., the render function or [propTypes](/docs/typechecking-with-proptypes.html#proptypes)) is not defined. If you need to access the same value within the child component, you should pass it as a different prop (ex: `<ListItemWrapper key={result.id} id={result.id} />`). While this may seem redundant, it's important to separate app logic from reconciling hints. | ||
К примеру, прочитать `this.props.key` из компонента (т.е. функции рендеринга или [propTypes](/docs/typechecking-with-proptypes.html#proptypes)) не удастся. | ||
Если дочернему компоненту тоже нужно это значение, передайте его под другим именем (например: `<ListItemWrapper key={result.id} id={result.id} />`). | ||
Это может показаться неудобным, но помогает разделить логику приложения от специальных инструкций для самого React. |
