var source = Array(1000000).fill(1).map((_, i) => Math.random());

Tests:

Array
const arrayResult = source .map(n => n * 2) .filter(n => n > 0.5) .reduce((m, c) => Math.max(m, c));
RxJs
const transducerResult = rxjs.of(source).pipe( rxjs.operators.map(n => n * 2), rxjs.operators.filter(n => n > 0.5), rxjs.operators.reduce((m, c) => Math.max(m, c)) ).subscribe(console.log);
