Enable the use of unfamiliar techniques on object

I am facing a challenge with an object that contains multiple method names which are not known at compile time. The signature of these methods always remains the same, but I am unsure about how to handle this scenario. I attempted to utilize an index type solution as shown below:

interface List<T> extends Array<T> {
    [key: string]: (...arg0: any[]) => List<T>
    [key: string]: () => List<any>
    each(fn: Function): void
    each(...args: any[]): void
    toArray(): T[]
}

Unfortunately, TypeScript throws an error stating it cannot accommodate other method signatures within this structure:

Property 'each' of type '{ (fn: Function): void; (...args: any[]): void; }' is not assignable to string index type '(...arg0: any[]) => List'.

This may be an unconventional requirement, but I am in need of a solution. How can this specific issue be addressed in TypeScript?

Answer №1

class CustomList<T>{
[key: string] : ((...params) => any) | (() => CustomList<any>);
iterateOver: ((func: Function) => void) | ((...arguments: any[]) => void);
convertToArray : () => T[];

}

Does this meet your requirements?
