export class Model{
code:string;
desc: string;
}
export class component {
observable$= Observable<Model>;
}
i have the observable$ of type Model consuming from a service. Now observable$ having the following values
[{code:1 desc: 'green'} {code:2, desc:'green'}, {code:3, desc:'yellow'}]
How to filter the observable to contain only code=1 & code=2. I have tried the following way and it wont work.
observable$.pipe(
map(res => res.filter(item => item.code ==1 && item.code==2))
);
expected output
[{code:1 desc: 'green'} {code:2, desc:'green'}]
