has-integer-log.js

const checkAndLog = x => {
  console.log('passed by', x)
  return Number.isInteger(x)
}

const xs = ['a', 1, 2, 3, 4]
const ys = ['a', 'b', 'c', 'd', 'e']

const xsHasinteger = xs.some(checkAndLog)
// passed by a
// passed by 1
console.log(xsHasinteger) // true

const ysHasinteger = ys.some(checkAndLog)
// passed by a
// passed by b
// passed by c
// passed by d
// passed by e
console.log(ysHasinteger) // false
