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.
רוב ה-props ב-JSX אלמנט מועברים לקומפוננטה, למרות זאת, יש שני props מיוחדים (`ref` ו- `key`) אשר משמשים את React, ולכן הם לא מועברים לקומפוננטה.

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.
לדוגמא, לנסות לגשת ל-`this.props.key` מהקומפוננטה (כלומר פונקציית render או [propTypes](/docs/typechecking-with-proptypes.html#proptypes)) אינו מוגדר. אם אתה צריך לגשת לאותו ערך בתוך הקומפוננטת ילד, אתה צריך להעביר אותו כ-prop אחר (לדגומא: `<ListItemWrapper key={result.id} id={result.id} />`). למרות זה נראה מיותר, זה חשוב להפריד את הלוגיקה של האפליקציה מרמזי reconciling.
