There are (at least) 2 ways to define an array in Typescript. To the best of my knowledge they both do the same thing with differing syntax.

Imagine we have the following type definitions

type Post = {  
  content: string  
type User = {  
  posts: Array<Post>,  
  other_posts: Post[]  

We can define an array of Post by using Array<Post> or Post[].

For purely syntactic reasons I lean towards Array<Post> as I read it as β€œan Array of Post objects”
