JavaScript Object needs method "unset" for immutable removing property from object

You can use rest operator in objects:

const {
  removedProp,
  ...restProps
} = myObject;

const {
  removedProp,
  ...restProps
} = myObject;

And you will have eslint error "'removedProp' is defined but never used eslint (no-unused-vars)"
It's not a solution, it's way to hack

And if you need delete deep property, your solution doesn't short and usable

ESLint is right. If you need to remove prop without using it then you probably doing something wrong.

For example, your application is Chat like Telegram. You have stored normalized list of contacts in Redux (immutable store)

var contacts = {
  153: { id: 154, username: ... },
  245: { id: 245, username: ... },
  ...
  455: { id: 455, username: ...},
}

And if you want to remove contact by id, how do you can to do it?
