while (i <= 1E5) arr[i] = i++;

Tests:

flatmap
const preArr = [] arr.flatMap(x => x % 12 && x % 5 && x % 3 ? x/100 : preArr)
reduce
arr.reduce((newArray, x) => { if (x % 12 && x % 5 && x % 3) { newArray.push(x / 100) } return newArray }, [])
filter.map true
arr.filter(x => true).map(x => x/100)
filter.map with condition
arr.filter(x => x % 12 && x % 5 && x % 3).map(x => x/100)
