in react to reference component properties not defined as arguments?

export default function SoftMount({
  children,
  child_ref,
  real_class_name,
  duration,
}) {
  
  return <div/>
}

usage:

<SoftMount unexpected_prop={"some_value"} />

Inside of <SoftMount />, how do I access unexpected_prop?

>Solution :

You can capture all remaining properties using the "rest parameters" sytax (...variable_name)

export default function SoftMount({
  children,
  child_ref,
  real_class_name,
  duration,
  ...other_props // This will collect all other props not destructured
}) {
  console.log(other_props.unexpected_prop); // "some_value"

  return <div/>
}
