Get angular Observable stream as array

Question

I have list, that should simulate the stream :

list = [
  {name : \'Str1\', age: 10},
  {name : \'Str2\', age: 10},
  {n         


        

Answer 1

The scan operator should do what you want

Observable.from(this.list)
.skip(this.currentPage * this.pageSize)
.take(this.pageSize)
.scan([], acc, curr) => {acc.push(curr); return acc;});
.subscribe(data => this.pagerList = data, console.error);
