TypeScript: is there a difference between Entity[] & array<Entity>? [duplicate]

Question

All in title,

e.g.

users: User[];
users: array<User>;

What is the difference? Is there one a better practice than the other?

nb: I couldn't find information about this & I see both in source code.

array isn't a built-in type. Did you mean Array? If so then, User[] is just syntactic sugar for Array<User>, and which version you use is purely up to your preferences, but I would prefer User[]. — p.s.w.g

users: User[]; is a valid type.

users: array<User>; is not a valid type. You will get an error Cannot find name 'array'.

You can create your interface like below.

export interface Person {
    users: User[];
}

export interface User {
    firstName: string;
    lastName: string;
}
