Optional type parameters for interfaces?

[raw hinge]

I am trying to create an interface in typescript that takes in parameters, but I want the parameters to be optional. Is this possible?

Example:

export interface MyInterface<T> {...}

let thing1: MyInterface = ...
let thing2: MyInterface<param> = ...

[celest axle]

assign a default type

[raw hinge]

additionally, I want T to extend MyInterface

so I tried export interface MyInterface<T extends MyInterface = void>

but I get error "Type 'void' does not satisfy the constraint 'MyInterface<void>"

[wheat cape]

default to never

or MyInterface

[raw hinge]

never strikes again! thank you so much
