How to take or manipulate data inside subscribe - Angular

Question

Unfortunately I can’t, even inside the subscribe, scroll through the variable fixtures$ I can send the data to html and show in the table. However I need to manipulate the data to save in the bank already in its own ". Component".

 for (var i = 0; i < this.fixtures$.length; i++) {
            this.fixtures$[i].name = this.fixture$[i].id +' '+ this.fixtures[i].name 
            } 

It didn’t work either.

After several and several attempts, I was able to make it work with the code below; /service/

    getFixtures(): Observable<any> {
      return this._http.get(this.baseUrl)
     .pipe(map(response => response));
  }

Component.

ngOnInit() {
this.simpleBet.getFixtures().subscribe(
  data => {
    this.fixtures$ = data.data;
    this.fixtures$.forEach(x =>

       console.log(this.fixtures$, x)

       )
       for (var i = 0; i < this.fixtures$.length; i++) {
       console.log( this.fixtures$[i].name = this.fixtures$[i].id +' '+ this.fixtures$[i].name[i]) 
        } 
  },
  error => {
    this.errorMessage = `${error.status}: ${JSON.parse(error.error).message}`;
  }
);

}
