QUESTION
I'm new to angular came from angularjs, and I'm confused about rxjs observable.
Example:
User.ts
...ANSWER
Answered 2019-Mar-06 at 06:05With you instruct Typescript that the return of
http.get
is an Observable
so it will infer the type of myUser
to Observable
. This is very helpful further in your application since the tooling will know what properties exist on your reponse types and if you did a mistake/typo. It will also fail during compile time if you access properties that don't exist. That is because http.get
is a generic method where you can specify the response type (but if you don't specify it, it uses any).
Without , typescript will just use the
any
type, which brings no additional benefit over plain javascript.
Also map(resp => { return resp; })
is useless and you can safely remove it.
