Interesting! So can Interface can only be used for objects, but Type cannot be used for objects?

@Chektinchan I've spent some time learning more on a topic and I think the ts documentation nails my whole blog post in 2 senteces.

Type aliases and interfaces are very similar, and in many cases you can choose between them freely. Almost all features of an interface are available in type, the key distinction is that a type cannot be re-opened to add new properties vs an interface which is always extendable.

@ummahusla And even though you can always use ‘&’ sign to extend a type with new properties :)
