How to pass an object to a function in React?

Question

JavaScript

Hi guys, I ran into such a problem:
For example, there is an object

let user = {
  age: 22,
  name: 'Boris'
}

How can I pass an example user.ageto a function to use it as a parameter in the future?

// здесь передаем
  let getUserData = () => {
    getUserParams(user.age)
  }
  // тут получаем как параметр
  let getUserParams = (age) => {
    // используем параметр
  }

If you do as I indicated above, then user.age === undefined

In React it looks like this:

// component
const UserComponent = ({user}) => {
    // вызываем здесь console.log(user.age) === 22
    let getUserData = () => {
      getUserParams(user.age) // если вызвать console.log(user.age) здесь то === андефайнед
    }

  return(
    //code
  )
}
