老師請問這裡的 e.preventDefault() 是要阻止什麼？為什麼要寫這個呢？ 不傳e進去可以嗎？

export const Option: FC = ({value, label, disabled, children, index}) => {
const { onSelect, selectedValues, multiple } = useContext(SelectContext)
const isSelected = selectedValues.includes(value)
const classes = classNames(‘viking-select-item’, {
‘is-disabled’: disabled,
‘is-selected’: isSelected,
})
const handleClick = (e: React.MouseEvent, value: string, isSelected: boolean) => {
e.preventDefault()
if(onSelect && !disabled) {
onSelect(value, isSelected)
}
}
return (
<li key={index} className={classes} onClick={(e) => {handleClick(e, value, isSelected)}}>
{children || (label ? label: value)}
{multiple && isSelected && }

)
}
