I am trying to make a function that can receive some args together or none of the.

(This is a typings only question)

I have a base and a descendant type

I have one value of some tuple type, and I want to map it to a different tuple of a different type. The tuples are allowed to be heterogenous. Is there a way of performing this mapping without using the type cast in the example below?

I want UserSetting to throw an error at [k: number]: boolean; how can i achieve this ?

My scenario: I am trying to build a filter utility that takes an interfaces and at each stage it can eliminate few properties from the object, and you can chain multiple filter methods.

I’m implementing a type-safe shapeAdapter function in TypeScript that takes an original object, an adapt function to transform it, and a revert function to convert it back.

I’m making a package that lets you define “actions” and then “trigger” them. Actions are functions that take some payload and a callback to trigger more actions recursively.

I’m converting legacy project from JS to TS and I’m learning TS at the same time.
I’ve stumbled upon an endpoint that has many different variants of responses.
Let’s say I only know part of the types, like in example below:

I’ve added a simplified version of my problem here
