javascript - Property 'includes' is missing in type 'Subscription' -angular2 -

i have been trying array of objects node service oninit , assign component. able view data in service when try assign variable in component, below error. have included code well. please favour on this.all need take array service , assign finallist in component.

error in       c:/users/girija/documents/animapp/src/app/components/list.component.ts (28,5): type 'subscription' not assignable type 'any[]'.       property 'includes' missing in type 'subscription'. 

my code below: app.service.ts:

   public finallist=[]      getlist(){           return this.http.get('/api/list').subscribe(data=>{              this.finallist=json.parse(data['_body']);              return this.finallist;         })         } 

app.component.ts:

  totallist=[];      ngoninit() {         this.totallist=this.someservice.getlist();        } 

subscribe returns subscription object, not have looking for.

try this:

app.service.ts

getlist(): observable<any> {   return this.http.get('/api/list').map(data => data['_body']); } 

app.component.ts

totallist=[];  ngoninit() {   this.someservice.getlist().subscribe(data => this.totallist = data); }
