A Typescript interface featuring a method named 'create'

Currently, I am facing a challenge in creating a TypeScript definition for an external library that features a factory function named "new". The issue arises when attempting to add a function named "new" within the interface as it conflicts with the constructor's type.

Is there a workaround to avoid using the new keyword or make this type functional?

export interface Container {

  //I need this functionality, but as a regular function and not the constructor
  customFunction<T>(TConstructor: new () => T, locals?: object): T;

}

To achieve the desired outcome, you simply need to include a set of quotation marks:

export interface Container {

  //The following code snippet shows how to accomplish this with a standard function instead of a constructor
  'new'<T>(TConstructor: new () => T, locals?: object): T;

}

You should always include the method identifier when quoting:

export interface Box {

  'get'<U>(UConstructor: new () => U, data?: object): U;

}

declare let obj: Box;
obj.get(undefined!)
