Support an array of names

Could we have support for an array of values that returns an array.

e.g.

myProperties: string[] = nameof<Company>(o => o.Name, o => o.Address1, o => o.Address2);

transpiles to:

myProperties = ["Name", "Address1", "Address2"];

Maybe even call it namesOf?

This is merged and available now thanks to @cecilyth!

One important thing to note is that the following transform is not yet available…

nameof.toArray<SomeInterface, OtherInterface, SomeType>();

… we’ll have to wait for TypeScript to support calling functions with a variable number of type arguments (ex. nameof.toArray<...T>(): string[]). A workaround would be to just add a bunch of function declarations with different number of type arguments (ex. nameof.toArray<T1>(): string[]; nameof.toArray<T1, T2>(): string[]; ...etc...). Might be worth it to do that actually.

Perhaps it would also be good to implement something like nameof.toArray<T1, T2>((o1, o2) => [o1.test, o2.asdf]); and with more type parameters.

Anyway, something to think about for improving this. Please let me know if you would like any of these features.

Interesting idea. Perhaps the following?

nameof.toArray<Company>(o => [o.Name, o.Address1, o.Address2]);

Signatures:

function toArray<T>(func: (obj: T) => any[]): string[];
function toArray(...args: any[]): string[];
