Script Preparation code:

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

Tests:

filter().map()
arr.filter(x => x % 3).map(x => x/100)
flatMap()
arr.flatMap(x => x % 3 ? x/100 : [])
for loop
var accum = []; for (let i=0; i < arr.length; i++) { const x = arr[i]; if (x % 3) { accum.push(x/100) } }
