Can you explain the purpose of the bind function?

I've been diving into the world of Angular2 with TypeScript and stumbled upon a piece of code that has me scratching my head:

export var userServiceInjectables: Array<any> = [
  bind(UserService).toClass(UserService)
];

Can someone break down for me what exactly this code is doing?

Answer №1

The definition of providers has evolved over time and the old way of defining them in RC.6 is no longer valid.

Now, the syntax for defining providers is as follows:

providers: [UserService]

Alternatively, you can use the long form like this:

providers: [{provide: UserService, useClass: UserService}]
