How to destructure and reassign in one line using JavaScript

Question

I have an object adData and I need to extract some of it's properties, add some more properties to the extracted object and pass the object as parameter. I can do this using:

const params = {}; 
params.id = adData.id;  
params.status = adData.status; 
params.frequency = adData.frequency; 
params.user = getLoggedInUser(); 
callAnotherFunction(params)

Can I do the destructing and reassigning to new object in one line ? Something like:

const params = {id, status, frequency} = adData; 
params.user = getLoggedInUser(); 

Or

const params = {id, status, frequency, getLoggedInUser(): user} = adData; 

Now these both above syntaxes are wrong but is there any other way to do it using destructuring and without extracting the properties one by one

Answer 1

If you know what properties the object does have, and there aren't that many, you can list them and use rest syntax to gather the others into an object:

const { unwantedProp, ...params) = adData;
// use params

Otherwise, there isn't any incredibly simple syntax for what you want, though you could

const params = Object.fromEntries(
  Object.entries(adData).filter(([key]) => 
    ['id', 'status', 'frequency'].includes(key)
  )
);
