Iterating through and object property and putting the values inside variables in javascript

I’m trying to iterate through an object using the for...in loop to get the values of all its properties and put them inside variables. I’m stumbling on this.

What I would like to do is loop through the object properties, put the value inside a variable of the same the name as the property to use on them on another variable

somePromise.then(response => {  

  for (let property in response) {
    property = response[property]  // this doesn't work cause reuses the same variable
  }

  /// I take the value of each property from the loop and pass it down 
  user.updateInfoFromOldDB(
    userID,
    nguid,
    property1 
    property2,
    property3
    property4,
  )

  ...ommited_code
})
