Hello guys I would like to get your opinion on something, in Typescript is there a difference between :
return new ObjectType();
return {} as ObjectType;
Which one is more idiomatic or a better practice overall ? and are there any cons for each one ?

There is a huge difference and which to use depends on what ObjectType is
the new ObjectType() syntax is how you construct an instance of an ES6 class
{} is an empty object literal, a direct construction of an empty object
in this case you are casting it to the type ObjectType, which is a strange thing to do with something you are returning and probably breaking type safety
As to which is more idiomatic between classes and plain objects, that entirely depends on what you want to do with it, which programming paradigm you prefer etc.
e.g. people who like OOP tend to gravitate towards classes, people who prefer imperative or functional style programming tend to use plain objects more often

That's very interesting, thank you so much @austere scaffold !
