Script Preparation code:

var arr = [];
var i = 0;

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

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

Tests:

filter().map()
arr.filter(x => x % 3).map(x => x/100)
arr.filter(x => x % 3).map(x => x/100)
flatMap()
arr.flatMap(x => x % 3 ? x/100 : [])
arr.flatMap(x => x % 3 ? x/100 : [])
mapFilter(Boolean)
arr.map(x => x % 3 && x/100).filter(Boolean)
arr.map(x => x % 3 && x/100).filter(Boolean)
