Benchmark: reduce vs map,filter

Script Preparation code:

a = [];
for (let i = 0; i < 10000; i++) {
    a.push(Number(i) / 1000 * 1000);
}
var mapping = x => x % 5 !== 0 ? x : undefined;
var filtering = x => x;
var reducing = (acc, x) => {
    const value = mapping(x);
    if (filtering(value)) acc.push(value);
    return acc;
}

Tests:

map-filter
a.map(mapping).filter(filtering);
reduce
a.reduce(reducing,[]);
