I know I'm late for this question, but how about this one ?

from([1, 34, 65, 3, 7]).pipe(
    filter(item => item > 10),
    isEmpty(),
    map(hasNone => !hasNone),
).subscribe((e) => console.log(e))

It is solely based on RxJS operators, and has the advantage of closing the source as soon as one value passes the test.
