Script Preparation code:

some = (set, predicate) => {
    const values = set.values()
    let e
    let found = false
    while (!found && !(e = values.next()).done) {
      found = predicate(e.value)
    }
    return found
  }
a = Array.from({length: 800}, i => i)
s = new Set(a)

Tests:

fp-ts set
const r = some(s,(v) => v == 301 )
native set
const r = s.has(301)
native array
const r = a.some(v => v == 301)
