Script Preparation code:

a = [];
for (i = 0; i < 1000; i++) a.push(Number(i) / 1000);
var filtering = x => (x * 114514) % 1 > 0.5;
var mapping = x => x + 0.1919;
var reducing = (acc, x) => {
    if (filtering(x)) acc.push(mapping(x));
    return acc;
}
var reducingWithDestructuring = (acc, x) => {
    if (filtering(x)) {
        return [...acc, mapping(x)];
    }
    return acc;
}

Tests:

map-filter
a.filter(filtering).map(mapping);
