Developing a Universal Type in Typescript

Encountered an issue with generic types while working on a user-defined type(interface) structured like this:

IList1: {  
          prop1: string,  
          prop2: number,  
          prop3: string  
          .  
          .  
          . 
       }

IList2:...
IList3:...

After receiving a server-side response in the form of Array<Array<,IListx>>, attempted to create a function as follows:

function fun<T>(args:T):Array<Array<T>> {
  return Array<Array<typeof args>>;
}

Also tried declaring variables like this:

let a:fun<IList1> = ...;
let b:fun<IList2> = ...;
let x:fun<IListx> = ...;

This approach did not yield the desired outcome. Uncertain if this is the correct method for creating a generic type, seeking assistance to rectify the issue. Any guidance would be highly appreciated.

Answer №1

After experimenting a bit, I believe I have discovered a method that involves both defining and initializing:

function customFunction<T>():Array<Array<T>> {
  return Array<Array<T>>();
}


let x = customFunction<IList1>();
let y = customFunction<IList2>();

Everything worked as anticipated. It's possible there are even more effective solutions out there.
