Script Preparation code:

var arr = [];
var i = 0;

while (i <= 1E5) arr[i] = i++;

Tests:

filter().map()
arr.filter(x => x !== 0 && x % 3 && x !== 666).map(x => Math.round(x * Math.sqrt(x/100)))
flatMap()
arr.flatMap(x => (x !== 0 && x % 3 && x !== 666) ? Math.round(x * Math.sqrt(x/100)) : [])
reduce()
arr.reduce((acc, x) => { if (x !== 0 && x % 3 && x !== 666) { acc.push(Math.round(x * Math.sqrt(x/100))) } return acc }, [])
