Below is the code I am working with:
export interface IStartCreate1 {
(desc?: string, opts?: IDescribeOpts, arr?: Array<string | IDescribeOpts | TCreateHook>, fn?: TCreateHook): void;
tooLate?: boolean;
}
export interface IStartCreate2 {
(opts?: IDescribeOpts, arr?: Array<string | IDescribeOpts | TCreateHook>, fn?: TCreateHook): void;
tooLate?: boolean;
}
export interface IStartCreate3 {
(arr?: Array<string | IDescribeOpts | TCreateHook>, fn?: TCreateHook): void;
tooLate?: boolean;
}
export interface IStartCreate4 {
(fn: TCreateHook): void;
tooLate?: boolean;
}
export type IStartCreate = IStartCreate1 | IStartCreate2 | IStartCreate3 | IStartCreate4;
Now, consider an object like this:
const v = {
create: function(){} as IStartCreate
}
v.create([]);
Upon running this code snippet, I encounter the following error message:
Cannot invoke an expression whose type lacks a call signature.
It seems strange to me that an empty array does not match IStartCreate3.
I have explored similar questions on Stack Overflow regarding this particular error message, but I am still unable to resolve it!
